I am catching an exception in try catch blog. The method am using is:

try
{
//some code here;
}
catch(exception e)
{
response.clear();
response.Write("<h4>"+e.message+"</h4>");
}

The issue I am facing is while the exception is displaying, in the front end it is displaying the line and function which is causing the exception.

eg.--soap exception:Data base not found at exception.GetInfo() in c:/bsb/exception.cs at line 70;

I dont want to display the text being displayed in bold.

Please let me know how can i do it

Hello,

If I understand correctly, you wish to hide the path to the file generating the error, but still keep the source and error type.

I tried every error message using:

try
    {
        //generate error
    }
    catch (Exception ex) {
        Response.Clear();
        Response.Write("<h3> Data:" + ex.Data + "</h3>");
        Response.Write("<h3> HelpLink:" + ex.HelpLink + "</h3>");
        Response.Write("<h3> InnerException:" + ex.InnerException + "</h3>");
        Response.Write("<h3> Message:" + ex.Message + "</h3>");
        Response.Write("<h3> Source:" + ex.Source + "</h3>");
        Response.Write("<h3> StackTrace:" + ex.StackTrace + "</h3>");
        Response.Write("<h3> TargetSite:" + ex.TargetSite + "</h3>");
        Response.Write("<h3> ToString():" + ex.ToString() + "</h3>");
        Response.Write("<h3> GetBaseException():" + ex.GetBaseException() + "</h3>");
      }

After these tests, I think you may go for a combination of error messages, e.g.:
- ex.Source + ex.TargetSite + ex.Message
- ex.Source + ex.Message

A second possiblity is removing the address path. But, I think this is quite complicated, unless you know precisely how the exception looks like.

Another option would be to create your own exception message, or class (and override GetBaseException()), and use that.

Hope this helps!

Perhaps this:

XML

try
{
//some code here;
}
catch(exception e)
{
response.clear();
response.Write("<h4 style="font-weight:normal;">" + e.message + "</h4>");
}

Solution 1

Use e.ToString() instead - it gives just the error message without the location context.

Show me the code that generate the error, and the exception handling code you actually used.

Solution 4

In your web.config, change

<compilation debug="true"></compilation>

to

<compilation debug="false"></compilation>

Let me know if it works!

nope :(

Instead of e.Message try using e.Source

bsb25 16-Jun-11 7:45am

it will give only the exception source, not the message.

For ex for db exception its Database exception class.

check this out:

XML

try
{
//some code here;
}
catch(Exception ex)
{
Response.clear();
Response.Write("<h4>" + ex.Message.ToString() + "</h4>");
}
