Debug.Assert Method (Boolean, String, String)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Checks for a condition and displays two specified messages if the condition is false.

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

[ConditionalAttribute("DEBUG")]
public static void Assert(
	bool condition,
	string message,
	string detailMessage
)

Parameters

condition
Type: System.Boolean
The conditional expression to evaluate. If the condition is true, the specified messages are not displayed.
message
Type: System.String
A message to display.
detailMessage
Type: System.String
A detailed message to display.

Typically, the Assert method is used to identify logic errors during program development. Assert evaluates a specified condition. If the result is false, it sends diagnostics to the debugger.

The Assert(Boolean, String, String) overload displays two messages that you specify.

The default behavior displays an Assert dialog box when the application runs in user-interface mode, and outputs the messages to the debugger when in debug mode.

NoteNote:

The Assert method behaves differently in Windows Phone applications than it does in desktop applications. When an Assert occurs, a dialog box is displayed with two options, OK and Cancel. Cancel causes the debugger to break at the Assert statement, OK causes it to continue. If a debugger is not currently attached, you may attach one before you close the dialog box.
