The Environment.StackTrace property lists method calls in reverse chronological order, that is, the most recent method call is described first, and one line of stack trace information is listed for each method call on the stack. However, the Environment.StackTrace property might not report as many method calls as expected due to code transformations that occur during optimization.

The Environment.StackTrace property formats the stack trace information for each method call as follows:

"at FullClassName.MethodName(MethodParams) in FileName :line LineNumber "

The literal "at" is preceded by three spaces, and the entire substring starting with "in" is omitted if debug symbols are not available. The placeholders, FullClassName, MethodName, MethodParams, FileName, and LineNumber, are replaced by actual values, and are defined as follows:

The Environment.NewLine string terminates each line of the stack trace.

The following example gets the Environment.StackTrace property from within a series of nested calls.

using System;
public class TestCallStack {
    public void MyMethod1 () {
        MyMethod2();
    }
    public void MyMethod2 () {
        MyMethod3();
    }
    public void MyMethod3 () {
        Console.WriteLine("TestCallStack: {0}",
                          Environment.StackTrace);
    }
    public static void Main() {
        TestCallStack t = new TestCallStack();
        t.MyMethod1();
    }
}

Without debug symbols the output is

With debug symbols the output is
