Catch hosting exceptions

This or this exception exists when we call the WebService and WCF interfaces written in C # or Java,

If it cannot be captured correctly, it will cause the applicationProgramCrash.

After searching for information, I finally found the answer to the problem!

1: when calling the interface, select' Support for Common Language Runtime libraries/CLR'(Vs2005 is like this)

2: add

# Using <mscorlib. dll>
# Include <tchar. h>
Using namespace system;

3: where exceptions may occur, use

Try ()

{}

Catch (...)

{}

In this way, all hosting exceptions can be captured.

If you want to know what the exception is, use try () {} catch (exception * E ){}

If you know the exceptions, you can directly specify them in the Catch Block, such as catch (ioexception * IOE) and catch (securityexception * se)
