C# Type GetProperty(String, Type, Type[], ParameterModifier[])

Description

Type GetProperty(String, Type, Type[], ParameterModifier[]) searches for the specified public property whose parameters match the specified argument types and modifiers.

Syntax

Type.GetProperty(String, Type, Type[], ParameterModifier[]) has the following syntax.

public PropertyInfo GetProperty(
  string name,/* w  w w.jav a 2s.com*/
  Type returnType,
  Type[] types,
  ParameterModifier[] modifiers
)

Parameters

Type.GetProperty(String, Type, Type[], ParameterModifier[]) has the following parameters.

• name - The string containing the name of the public property to get.
• returnType - The return type of the property.
• types - An array of Type objects representing the number, order, and type of the parameters for the indexed property to get.
• types - -or-
• types - An empty array of the type Type (that is, Type[] types = new Type[0]) to get a property that is not indexed.
• modifiers - An array of ParameterModifier objects representing the attributes associated with the corresponding element in the types array. The default binder does not process this parameter.

Returns

Type.GetProperty(String, Type, Type[], ParameterModifier[]) method returns An object representing the public property that matches the specified requirements, if found; otherwise, null.

Example

The following example obtains a Type object corresponding to MyPropertyClass, and the indexed property of this class is retrieved using the arguments passed to the GetProperty method.

using System;/*from  w w  w  . j av  a  2 s .c  o  m*/
using System.Reflection;
public class MyPropertyClass
{
    private int [,] myPropertyArray = new int[10,10]; 
    // Declare an indexer. 
    public int this [int i,int j]
    {
        get 
        {
            return myPropertyArray[i,j];
        }
        set 
        {
            myPropertyArray[i,j] = value;
        }
    }
}
public class MyTypeClass
{
    public static void Main()
    {
            Type myType=typeof(MyPropertyClass);
            Type[] myTypeArray = new Type[2];

            myTypeArray.SetValue(typeof(int),0);
            myTypeArray.SetValue(typeof(int),1);

            PropertyInfo myPropertyInfo = myType.GetProperty("Item",
                typeof(int),myTypeArray,null);
            Console.WriteLine(myType.FullName + "." + myPropertyInfo.Name + 
                " has a property type of " + myPropertyInfo.PropertyType);
    }
}

The code above generates the following result.
