how to set the value to Exception.Message or this.message properties?
-
Hi all, how to set a value to custom exception message? I tried to set the value, since its a read only property couldnt able to set it...i tried it as follows public class Customexp:ApplicationException { public void frm(String mess) { this.Message="test"; this.Source = "kjashdfkj"; } } for this code, error is as follows Property or indexer 'System.Exception.Message' cannot be assigned to -- it is read only can anyone tell me how to solve this problem. the clear point is, i've to create an exception object and have to set the value for it. Regards babu
If you don't need to do any manipulation of the message (and this is generally not a good idea), you should set Message by calling the base constructor:
public class Customexp: ApplicationException { public Customexp(string message) : base (message) {} }the last thing I want to see is some pasty-faced geek with skin so pale that it's almost translucent trying to bump parts with a partner - John Simmons / outlaw programmer
Deja View - the feeling that you've seen this post before. -
You set the message in the constructor by using the message in the constructor for the base class:
public CustomExp() : base("The message.") {
this.Source = "The source.";
}--- It's amazing to see how much work some people will go through just to avoid a little bit of work.

Hello babu, This properties are virtual, which you can override in youre class.
public override string Message
{
get "test";
}public override string Source
{
get "test";
}Hope that helps! All the best, Martin
:confused: That won't even compile.
