I added output=AST; to the grammar options at the top of cs.g to print out the tree.

options
{language = 'CSharp2';
output=AST;
}

When I build up the project after the change I got this message:

The command ""C:\Program Files\Java\jre6\bin\java" -cp "C:\Program Files\Java\jre6\lib\antlr-3.3.jar" org.antlr.Tool -message-format vs2005 cs.g -make -Xconversiontimeout 2500 -Xmultithreaded" exited with code 3. C:\Users\AMD\Desktop\Complier\antlrcsharp100620\UnitTest\UnitTest.csproj 68 24 UnitTest

Am I missing something here?

You need to modify the following lines in UnitTest.csproj:

<JavaDir>C:\Program Files\Java\jre6\bin\java</JavaDir>
<JarDir>C:\Program Files\Java\jre6\lib</JarDir>

to

<JavaDir>path to java.exe</JavaDir>
<JarDir>C:\users\amd\desktop\compiler\antlrcsharp100620\browse\browse\Antlr.Runtime\CSharp2</JarDir>

The JavaDir path needs point to the location of "java.exe". Mine was "C:\Program Files (x86)\Java\jre6\bin\"

The JarDir needs to have the path to the "antlr-3.3.jar" file. I set the path from your error message above.
