Is there a way to catch two different exceptions and process them in one catch block in .NET?
I'm thinking of something like
try {}
catch(OverflowException ex1, FormatException ex2)
{
}
I 开发者_如何学运维know I can use functions to reuse redundant logic in my catch blocks but I'm still curious as to whether a shorthand method exists for this.
No shorthand method exists. From §B.2.5 of the C# 3.0 specification, the grammar describes how a specific catch clause may only have a single class-type
and an optional identifier
:
try-statement: try block catch-clauses try block finally-clause try block catch-clauses finally-clause catch-clauses: specific-catch-clauses general-catch-clauseopt specific-catch-clausesopt general-catch-clause specific-catch-clauses: specific-catch-clause specific-catch-clauses specific-catch-clause specific-catch-clause: catch ( class-type identifieropt ) block general-catch-clause: catch block
Is there a reason you can't catch Exception and use that?
You could derive both OverflowException and FormatException from a common base and catch the base.
try {} catch(exceptionBase ex1) { }
See here for quite a bit more nuts-and-bolts information about try/catch/finally blocks.
as per my knowledge its not possible.
you can try
try {}
catch(Exception ex)
{
if (ex is OverflowException )
{
//do this
}
else if(ex is FormatException )
{
//do this
}
}
