Contract.Assume Method (Boolean, String)

Instructs code analysis tools to assume that a condition is true, even if it cannot be statically proven to always be true, and displays a message if the assumption fails.

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

[ConditionalAttribute("DEBUG")]
[ConditionalAttribute("CONTRACTS_FULL")]
public static void Assume(
	bool condition,
	string userMessage
)

Parameters

condition
Type: System.Boolean

The conditional expression to assume true.

userMessage
Type: System.String

The message to post if the assumption fails.

If userMessage is not a constant string literal, the contract may not be understood by tools.

At run time, using this method is equivalent to using the Assert(Boolean, String) method.
