Parameters
name
Type: StringThe name of the member to invoke.
- bindingFlags
Type: BindingFlags
parameterTypes
Type: array<Type[]An array of Type objects that represents the number, order, and type of the parameters for the method to access.
-or-
An empty array of the type Type (that is, Type[] types = new Type[0]) to get a method that takes no parameters.
args
Type: array<Object[]Any arguments that the member requires.
culture
Type: CultureInfoThe CultureInfo object that represents the globalization locale to use, which might be necessary for locale-specific conversions, such as converting a numeric String to a Double.
-or-
nulla null reference (Nothing in Visual Basic) to use the current thread's CultureInfo.
typeArguments
Type: array<Type[]An array of type arguments to use when invoking a generic method.
Return Value
Type: Object
Examples
The following code is in the application that you are testing. It contains a generic method that you want to test, TestThisMethod<T>.
internal class Customer
{
internal T TestThisMethod<T>(T value)
{
return (value);
}
public Customer()
{
}
}
The following code is a test method in your unit test. It shows how to pass a type argument, in the final Type[] parameter, when it invokes the method that you are testing:
[TestMethod]
public void TestSetCustomerId()
{
PrivateObject po = new PrivateObject(typeof(Customer));
int id = 100;
int actual = (int)po.Invoke("TestThisMethod", new Type[] { typeof(int) }, new Object[] { id }, new Type[] { typeof(int) });
Assert.AreEqual(actual, id);
}
