.NET Framework Exceptions Throwing an exception from a different method while preserving its information
Example
Occasionally you'd want to catch an exception and throw it from a different thread or method while preserving the original exception stack. This can be done with ExceptionDispatchInfo:
using System.Runtime.ExceptionServices;
void Main()
{
ExceptionDispatchInfo capturedException = null;
try
{
throw new Exception();
}
catch (Exception ex)
{
capturedException = ExceptionDispatchInfo.Capture(ex);
}
Foo(capturedException);
}
void Foo(ExceptionDispatchInfo exceptionDispatchInfo)
{
// Do stuff
if (capturedException != null)
{
// Exception stack trace will show it was thrown from Main() and not from Foo()
exceptionDispatchInfo.Throw();
}
}
