ParameterInfo.IsOut Property

 

Gets a value indicating whether this is an output parameter.

Namespace:   System.Reflection
Assembly:  mscorlib (in mscorlib.dll)

member IsOut : bool with get

Property Value

Type: System.Boolean

true if the parameter is an output parameter; otherwise, false.

This method depends on an optional metadata flag. This flag can be inserted by compilers, but the compilers are not obligated to do so.

This method utilizes the Out flag of the ParameterAttributes enumerator.

To get the ParameterInfo array, first get the method or the constructor and then call MethodBase.GetParameters.

The following example shows how to test method parameters for the ParameterAttributes.In, ParameterAttributes.Out, and ParameterAttributes.Optional attributes.

The example contains a DefineMethod method that does the following:

After executing DefineMethod, the example searches the assemblies that are currently loaded until it finds the dynamic assembly. It loads MyType from the assembly, gets a MethodInfo object for the MyMethod method, and examines the parameters. The example uses the IsIn, IsOut, and IsOptional properties to display information about the parameters.
