Nested try Blocks

You can insert a try block inside another try block to form nested try blocks. An unlimited number of nested try blocks can be written inside each other. Any uncaught exceptions of an inner try block moves through each of its outer try blocks one by one from innermost to outermost in search of a matching catch block. If no match is found, the runtime's default exception handler will handle the exception as shown earlier.

Listing 19.5 provides a simple example of one try-catch block nested inside another try block.

Listing 19.5. NestingTryBlocks.cs
