示例1: OldMethod
//引入命名空间
using System;
using System.Reflection;
public class Example
{
// Mark OldProperty As Obsolete.
[ObsoleteAttribute("This property is obsolete. Use NewProperty instead.", false)]
public string OldProperty
{ get { return "The old property value."; } }
public string NewProperty
{ get { return "The new property value."; } }
// Mark OldMethod As Obsolete.
[ObsoleteAttribute("This method is obsolete. Call NewMethod instead.", true)]
public string OldMethod()
{
return "You have called OldMethod.";
}
public string NewMethod()
{
return "You have called NewMethod.";
}
public static void Main()
{
// Get all public members of this type.
MemberInfo[] members = typeof(Example).GetMembers();
// Count total obsolete members.
int n = 0;
// Try to get the ObsoleteAttribute for each public member.
Console.WriteLine("Obsolete members in the Example class:\n");
foreach (var member in members) {
ObsoleteAttribute[] attribs = (ObsoleteAttribute[])
member.GetCustomAttributes(typeof(ObsoleteAttribute),
false);
if (attribs.Length > 0) {
ObsoleteAttribute attrib = attribs[0];
Console.WriteLine("Member Name: {0}.{1}", member.DeclaringType.FullName, member.Name);
Console.WriteLine(" Message: {0}", attrib.Message);
Console.WriteLine(" Warning/Error: {0}", attrib.IsError ? "Error" : "Warning");
n++;
}
}
if (n == 0)
Console.WriteLine("The Example type has no obsolete attributes.");
}
}输出：
Obsolete members in the Example class: Member Name: Example.OldMethod Message: This method is obsolete. Call NewMethod instead. Warning/Error: Error Member Name: Example.OldProperty Message: This property is obsolete. Use NewProperty instead. Warning/Error: Warning
