The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets or sets a value indicating whether the application is running in user-interface mode.

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

public bool AssertUiEnabled { get; set; }

Property Value

Type: System.Boolean

true if user-interface mode is enabled; otherwise, false.

The following code example calls a function that calls the Fail(String, String) method to log an error message if the function throws an exception. If the AssertUiEnabled property is false, the method also writes the error message to the console.

// Compute the next binomial coefficient and handle all exceptions.
    result = CalcBinomial(possibilities, iter);
catch(Exception ex)
    string failMessage = String.Format("An exception was raised when " +
        "calculating Binomial( {0}, {1} ).", possibilities, iter);
    defaultListener.Fail(failMessage, ex.Message);
    if (!defaultListener.AssertUiEnabled)
        Console.WriteLine(failMessage+ "\n" +ex.Message);
