Yes it throws exception..
Assembly LoadedAssembly = Assembly.LoadFile(@"c:\WINDOWS\assembly\mscorlib.dll");
Exception Occured: The system cannot find the file specified. (Exception from HR
ESULT: 0x80070002)
I tried both Load and LoadFile, getting the similar exception. Any clues?
Thanks

The issue that you have here is that there is no file "c:\WINDOWS\assembly\mscorlib.dll". If you go to the command line and type in dir c:\windows\assembly you will see that it lists directories. The version that you see in the Windows shell is a wrapper to make it convenient for managing GAC entries.

Yes, you are correct. Not aware of this point...
But how to find out the info about the dll which are in GAC, (only know the dll name)?
I am really struck here, Thanks for your help.

If you only know the DLL name, then you should use Assembly.Load(); Here's an example:
Assembly assem = Assembly.Load("mscorlib.dll");

It works only with mscorlib.dll, if you try with some other dlls it fails... I am trying to build an application which needs the full deatils of the dll and it uses this information to generate a binding file.

Well, the hack way to do this would be:
Assembly assem = Assembly.Load("mscorlib.dll");
if (assem != null)
{
string path = System.IO.Path.GetDirectoryName(assem.Location);
assem = Assembly.LoadFrom(System.IO.Path.Combine(path, "System.Xml.dll"));
}

In addition to what Pete said... why do you want to load that particular DLL? If you want to look at the contents of mscorlib.dll, I suggest you fire up wincv.exe. If you want to load any DLL, verify the path and use Assembly.LoadFile().
I think relative paths will work with Assembly.LoadFile(), but if it blows up, Path.GetFullPath() is your friend.

Assembly.Load loads an assembly which is in the same directory with your application's executable.
Try Assembly.LoadFile or Assembly.LoadFrom but then your application can only run in FullTrust for security reasons.

When using Microsoft Visual Studio .NET, are there symbols defined by default with which I can determine which .NET framework is being used for the compilation?
I'm writing a custom control that inherits System.Windows.Forms.PictureBox. I'd like to override the OnMouseHover event handler but obviously this would not compile when I use the control in a .NET Compact Framework sollution.
So I was hoping to embrace the override with the #if compiler directive - something like this:
#if FULLFRAMEWORK<br />
protected override void OnMouseHover(EventArgs e)<br />
{<br />
base.OnMouseHover(e);<br />
}<br />
#endif
However, there is obviously no such symbol as FULLFRAMEWORK and I would prefer not to have to define it in every one of my projects that use this control. Is there a symbol that is defined by default that I could use for this purpose?

Hi,
AFAIK there are no predefined symbols.
I usually define either NET11 or NET20 in my Visual projects to discern different
.NET versions...

Hi all,
iam new to .net,iam getting problem at parsing the file.My sample file contains key value pair data,and key value is seperated by space and field is seperated by line.This is the sample code:

BILLTYPE 1|
BILLTEMPLATE 3|

In above file GENEVAVERSION 5.0 is one key value field it is seperated by space and each fields are seperated by pipe symbol and each is in new line.
my problem is how to parse this file as xml.pls send me some sample code it is more helpful for me.
Thanks&Regards

hi sandeep
so first we have to seperate the key value pair.so how to seperate them .pls help me in this situation.
Thanks&Regards

HI Renu
What you want to do with the file ? Why are you writing the file in this format then ? You can read this file as txt only you have to develop logic for that
Thanks and Regards

Hi sandeep

Thanks&Regards

We can do that only you have to think about logic see the code below
<br />
StreamReader streamreader=File.OpenText(Server.MapPath("TextFile.txt"));<br />
while (!streamreader.EndOfStream)<br />
{<br />
string line= streamreader.ReadLine();<br />
string[] values= line.Split(' '); <br />
<br />
}<br />
Thanks and Regards
Sandeep

Also each line contains only one key value pair or more ? Why pipe then ?
Thanks and Regards

pipe symbol is seperate the each key value pair

You could use the StreamReader.ReadLine method to read the file line by line and the String.Split method allows you to split each line according to your needs. Take a look at the documentation of both methods to get examples.

You must learn to exercise some patience. It is bad manners to repose a question shortly after you've posted the original, and yes I do count 17 hours as a short time. You have to understand that people on this site give their time freely, and that they help where they can.
You aren't paying for support, so while your problem may be mind bogglingly urgent to you, it might not even make my top 100 of things to do today. More importantly, help can come from any area of the world so the person who may be able to help you may be doing something else such as sleeping - as hard as it may be for you to believe, some of us do have lives outside the boards.

I have a question regarding the collection designer.
I have written a class "MyCollection" with ICloneable interface.
public class MyCollection: ICloneable
{
int a1 = 1;
string a2 = "abc";
MyCollection() {}
MyCollection( int _a1 )
{
a1 = _a1;
}
MyCollection( int _a1, string _a2 )
{
a1 = _a1;
a2 = _a2;
}
public object Clone()
{
return new MyCollection(a1, a2);
}
}
and use it in a component "Component1". Inside the Component1, I designed 2 properties, P1 and P2, P1 type is SqlParameter[] and another one P2 type is MyCollection[].
private SqlParameter[] p1;
public SqlParameter[] P1
{
get { return p1; }
set { p1 = value; }
}
private MyCollection[] p2;
public MyCollection[] P2
{
get { return p2; }
set { p2 = value; }
}
When I added the component into my form, I can see P1 and P2 in the property grid. For the P1, I can add the new SqlParameter object without problem. But for the P2, I can add but nothing can be saved. After I reopen the designer, P2 is still null. When I can view the design code directly:
this.component11.P1 = new System.Data.SqlClient.SqlParameter[] {
new System.Data.SqlClient.SqlParameter("", System.Data.SqlDbType.NVarChar),
new System.Data.SqlClient.SqlParameter("", System.Data.SqlDbType.NVarChar, 45)};
The designer only create SqlParameter object for P1. But no code for P2.
I have coded the ICloneable interface. However, is there any I still missed in coding the MyCollection class? Any information are appreciate.

Hi all,
I can solve this by specified "public" to the constructors of the MyCollection. Thanks a lot.

BUG1)
Prefer IClonable<t>. It does not exist, you can create one. Or use mine below:
interface IClonable<t>
{
T Clone();
}
BUG2)
Change:
public object Clone()
{
return new MyCollection(a1, a2);
}
TO
public object Clone()
{
return new MyCollection(a1, (string)a2.Clone());
}
because string is NOT a value type and the same refernce exists in each clone not the copy if you do it your way. So if you change the string in ony clone it is also changed for the other clones
BUG3) Never return arrays from Properties, use Collection or better Collection<t> where possible without a set accessor. You can still add items to a Collection or Collection<t> without set accessor.
Hope it helps...
