Метод Описание
BuildErrorMessage ( object value, Type typeOperand, bool isSameType ) : string

Builds the error message related to the type comparison. This should be called only if the test failed (no matter it is negated or not). Warning: Should not call this method with nullable types. Indeed, the Nullable types are treated specially by CLR and it is impossible to have a boxed instance of a nullable type. Instead, boxing a nullable type will result in a null reference (if HasValue is false), or the boxed value (if there is a value).
BuildErrorMessageForNullable ( Type instanceType, Type expectedType, object value, bool isSameType ) : string
InheritsFrom ( IChecker checker, Type expectedBaseType ) : void

Checks that an instance is in the inheritance hierarchy of a specified type.
IsDifferentType ( Type instanceType, Type expectedType, object value ) : void

Checks that a type is not the expected one.
IsInstanceOf ( object instance, Type expectedType ) : void

Checks that an instance is of the given expected type.
IsNotInstanceOf ( object instance, Type typeNotExpected ) : void

Checks that an instance is not of the given expected type.
IsSameType ( Type instanceType, Type expectedType, object value ) : void

Checks that a type is the same as the expected one.

BuildErrorMessage() публичный статический Метод

Builds the error message related to the type comparison. This should be called only if the test failed (no matter it is negated or not). Warning: Should not call this method with nullable types. Indeed, the Nullable types are treated specially by CLR and it is impossible to have a boxed instance of a nullable type. Instead, boxing a nullable type will result in a null reference (if HasValue is false), or the boxed value (if there is a value).
public static BuildErrorMessage ( object value, Type typeOperand, bool isSameType ) : string
value object The checked value.
typeOperand System.Type The other type operand.
isSameType bool A value indicating whether the two types are identical or not. true if they are equal; false otherwise.
Результат string

expectedBaseType System.Type The Type which is expected to be a base Type of the instance.
Результат void

IsDifferentType() публичный статический Метод

Checks that a type is not the expected one.
