Hi all,
Why am I getting a null value to the InnerException object?
Because you haven't set it to anything, so it still has the default
value of null. You need to set it explicitly when you catch and
rethrow.
Can anyone elaborate using examples?
Yes:
static void ThrowSomething() {
throw new Exception("This is the first exception.");
}
static void CatchAndRethrow() {
try {
ThrowSomething();
}
catch (Exception ex) {
// Second parameter is the inner exception
// It preserves details of the initial error.
throw new Exception("This is the rethrown exception.", ex);
}
}
static void Main() {
try {
CatchAndRethrow();
}
catch (Exception ex) {
if (ex.InnerException != null)
Console.WriteLine("Inner Exception: " +
ex.InnerException.ToString());
else
Console.WriteLine(ex.Message);
}
Console.ReadLine();
} // end Main()
