well in both cases you should know what return type to expect so...
var orderByDate = from dr in dsR.Tables["MyTable"].AsEnumerable()
Where (int)dr["ReportID"] == 3
select dr;
and...
var orderByDate = from dr in dsR.Tables["MyTable"].AsEnumerable()
Where (string)dr["ReportName"] == "Carl"
select dr;
or ToString() them both and compare them as strings...
var orderByDate = from dr in dsR.Tables["MyTable"].AsEnumerable()
Where dr["ReportID"].ToString() == "3"
select dr
and...
var orderByDate = from dr in dsR.Tables["MyTable"].AsEnumerable()
Where dr["ReportName"].ToString() == "Carl"
select dr;

You do not need to use convert here since, p_value is already a string.
1. You can use return type as object. The only thing is that you will have to cast the return value.
2. You can also go for overloading.
3. If convert is the only task, why do you even need this method?

Well, you could accomplish this using generics. Here's one way:
private T CastTo<T>(string value)
{
if (typeof(T) == typeof(int))
{
int output = 0;
int.TryParse(value.ToString(), out output);
return output;
}
}Obviously, this isn't perfect because you have to add a load of these cases - but it is doable. You would call is using:
.Where CastTo<int>("44") == 44

this is the problem,
how to send in the right type.
the type is stored in string variable.
.Where CastTo<int>("44") == 44
it would look something like this.
string type="int";
.Where CastTo< type >("44") == 44

No, I don't think you can. You can return an object of course and do your thing with that afterwards.
You can return a generic T, but without generic type constraints you might be limited to what you can actually do in your method.
static T TMethod<T>(T value)
{
return value;
}

private object castTo(string typeName, object value)
{
Type castingType = Type.GetType(typeName);
return Convert.ChangeType(value, castingType);
}
That doesn't use generics, and it isn't type safe, but it does have the same method signature and have almost identical behaviour (I think you'll need to fully specify the type name though)
For a generic version, try this:
private T castTo<T>(object value)
{
Type castingType = typeof(T);
return (T)Convert.ChangeType(value, castingType);
}
It's type safe and far better-looking. One niggle though - the converted type must implement IConvertible

How to find Internet Explorer target folder, i.e., the IE installation folder in a System through c# code?
I want inject a dll in IE installation folder, In c# How can I do this through a MSI setup?
|
|
|
|
|
well Internet Explorer puts itself in the program files, and as far as I know it is always in 'Internet Explorer' so maybe the following will work for you...
string IEFolderPath = Environment.GetFolderPath(Environment.SpecialFolder.ProgramFiles) + "\\Internet Explorer\\";
Of Course, I don't know this for sure, I suppose you could look in the system registry settings and see if the installation folder is stored in there somewhere

Thank you vary much for your help.

I have used following AT commands
1: "AT"
2: "AT+CMGF=0" // 1 for text mode but it doesn't work
3: "AT+CSCS=\"8859-1\"
4: "AT+CPMS=\"SM\""
5: "AT+CMGL=4"

Assuming the name of your menu is MenuStrip1, then create a new ToolStripMenuItem and add it to the DropDownItems collection of MenuStrip1

He practically did just give you it as code. If you cant work out the code from what he said then you are way out of your league with what you are trying to do. You need to get a book on the basics of .Net, possible even programming in general if all you do is copy and paste code.

Hi,
could anyone help me how to send sms using windows application c#
how to make that
Thanks & Regards
Nath

Some firms run web services which you interface with and use to send the text
You can usually plug a phone into the serial port and manually send the data using it's antenna
You could send an email to the phone and hope that it gets delivered as a text message

i have to send sms using windows application. If there is anything please
let me know
|
|
|
|

I already have. Those are the three main approaches to sending an SMS. Windows application, WPF or console application - they will (almost) all use one of those three approaches. You simply have to investigate which of those would be most practical to you, and research it
