C# in a Nutshell

Name

Cordbg.exe — Command-line debugger

Synopsis

cordbg [program [program-arguments]] [!command ...]

Description

This is a general source-level, command-line debug utility for MSIL programs. It’s a very useful tool for C# source debugging (make sure you compiled your program with /debug). Source for cordbg is available in the \Tool Developers Guide directory. You can start cordbg with the name of a program and the arguments to pass to that program. You can also supply one or more commands (prefixed with !) on the command line.

After you launch cordbg, you are greeted by the (cordbg) prompt, where you can type commands until you exit cordbg with the quit command.

Sample Sessions

Set a breakpoint, start the program, and step through a few lines of code:
