Gets current stack trace information.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

public static string StackTrace { get; }

Property Value

Type: System.String

A string containing stack trace information. This value can be String.Empty.

The 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 StackTrace property might not report as many method calls as expected due to code transformations that occur during optimization.


For a hierarchical view of the stack trace information by class, use the StackTrace class.

The 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 full name of the class, including the namespace.


The name of the method.


The list of parameter type/name pairs. Each pair is separated by a comma (","). This information is omitted if MethodName takes no parameters.


The name of the source file where the MethodName method is declared. This information is omitted if debug symbols are not available.


The number of the line in FileName that contains the source code from MethodName for the instruction that is on the call stack. This information is omitted if debug symbols are not available.

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

The following example demonstrates the StackTrace property.

// Sample for the Environment.StackTrace property
using System;

class Sample 
    public static void Main() 
    Console.WriteLine("StackTrace: '{0}'", Environment.StackTrace);
This example produces the following results:

StackTrace: '   at System.Environment.GetStackTrace(Exception e)
   at System.Environment.GetStackTrace(Exception e)
   at System.Environment.get_StackTrace()
   at Sample.Main()'
