The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Gets the Type of this parameter.

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

public virtual Type ParameterType { get; }

Property Value

Type: System.Type

The Type object that represents the Type of this parameter.

This method depends on an optional metadata and might not be available in all compilers.

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

The following example shows how to get ParameterInfo objects for the parameters of a method, and then use the ParameterType property to display the type of each parameter.

 using System;
 using System.Reflection;

 class parminfo
    public static void mymethod (
       int int1m, out string str2m, ref string str3m)
       str2m = "in mymethod";

    public static int Main(string[] args)

       //Get the ParameterInfo parameter of a function.

       //Get the type.
       Type Mytype = Type.GetType("parminfo");

       //Get and display the method.
       MethodBase Mymethodbase = Mytype.GetMethod("mymethod");
       Console.Write("\nMymethodbase = " + Mymethodbase);

       //Get the ParameterInfo array.
       ParameterInfo[]Myarray = Mymethodbase.GetParameters();

       //Get and display the ParameterInfo of each parameter.
       foreach (ParameterInfo Myparam in Myarray)
          Console.Write ("\nFor parameter # " + Myparam.Position 
             + ", the ParameterType is - " + Myparam.ParameterType);
       return 0;

 This code produces the following output:


Mymethodbase = Void mymethod(Int32, System.String ByRef, System.String ByRef)
For parameter # 0, the ParameterType is - System.Int32
For parameter # 1, the ParameterType is - System.String&
For parameter # 2, the ParameterType is - System.String&
