示例1: MyAttribute
//引入命名空间
using System;
using System.Reflection;
// Define a custom attribute with one named parameter.
[AttributeUsage(AttributeTargets.Parameter)]
public class MyAttribute : Attribute
{
private string myName;
public MyAttribute(string name)
{
myName = name;
}
public string Name
{
get
{
return myName;
}
}
}
// Define a class which has a custom attribute associated with one of the
// parameters of a method.
public class MyClass1
{
public void MyMethod(
[MyAttribute("This is an example parameter attribute")]
int i)
{
return;
}
}
public class MemberInfo_GetCustomAttributes
{
public static void Main()
{
// Get the type of the class 'MyClass1'.
Type myType = typeof(MyClass1);
// Get the members associated with the class 'MyClass1'.
MethodInfo[] myMethods = myType.GetMethods();
// Display the attributes for each of the parameters of each method of the class 'MyClass1'.
for(int i = 0; i < myMethods.Length; i++)
{
// Get the parameters for the method.
ParameterInfo[] myParameters = myMethods[i].GetParameters();
if (myParameters.Length > 0)
{
Console.WriteLine("\nThe parameters for the method {0} that have custom attributes are :", myMethods[i]);
for(int j = 0; j < myParameters.Length; j++)
{
// Get the attributes of type 'MyAttribute' for each parameter.
Object[] myAttributes = myParameters[j].GetCustomAttributes(typeof(MyAttribute), false);
if (myAttributes.Length > 0)
{
Console.WriteLine("Parameter {0}, name = {1}, type = {2} has attributes: ",
myParameters[j].Position, myParameters[j].Name, myParameters[j].ParameterType);
for(int k = 0; k < myAttributes.Length; k++)
{
Console.WriteLine("\t{0}", myAttributes[k]);
}
}
}
}
}
}
}输出：
The parameters for the method Void MyMethod(Int32) that have custom attributes are :
Parameter 0, name = i, type = System.Int32 has attributes:
MyAttribute
The parameters for the method Boolean Equals(System.Object) that have custom attributes are :
