Set the message property of the exception in the constructor.
|
|
|
|

Did you call it right:
public MyException : ApplicationException<br />
{<br />
public MyException(string message) : base (message)<br />
{<br />
}<br />
}
|
|
|
|
|
|
Then the exception should have the message that is passed in to the constructor. Which is as it should be.

I explained how you do that in the other thread. If you didn't create mutiple threads about the same thing, the confusion would be less.

Set the value of message in the constructor, as in the examples given in the other thread you started.

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

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

 That won't even compile.

Sorry,
public override string Message
{
get
{
return "test";
}
}
public override string Source
{
get
{
return "test";
}
}

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.";
}

Hello Guffa,
Isn't Source also ReadOnly (Only get accessor)?
All the best,

thank you for your kind reply.The this.source is working. i need to set the value to this.message. can you tell me for that
babu

I already told you how to set the message. Read my previous post.
If you don't understand it, explain what it is that you don't understand.

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) {}
}

You set it in the constructor by calling the base constructor.

Don't you just get sick of saying the same thing over and over again? It's bad enough when it's to different people, but when it's to the same person, arggghhhhh!!!!!

Add to that the fact that You, me and Guffa have all told him what to do.
