Type.FilterName 字段

定义

命名空间:

System

程序集:

System.Runtime.dll

表示用于名称的区分大小写的成员筛选器。 此字段为只读。

public: static initonly System::Reflection::MemberFilter ^ FilterName;

public static readonly System.Reflection.MemberFilter FilterName;

 staticval mutable FilterName : System.Reflection.MemberFilter

Public Shared ReadOnly FilterName As MemberFilter 

字段值

MemberFilter

示例

下面的代码示例获取与用户定义 Application 类型关联的方法。

// Get the set of methods associated with the type
array<MemberInfo^>^ mi = Application::typeid->FindMembers(
   (MemberTypes)(MemberTypes::Constructor | MemberTypes::Method),
   (BindingFlags)(BindingFlags::Public | BindingFlags::Static |
      BindingFlags::NonPublic | BindingFlags::Instance | BindingFlags::DeclaredOnly),
   Type::FilterName, "*" );
Console::WriteLine( "Number of methods (includes constructors): {0}", mi->Length );

// Get the set of methods associated with the type
MemberInfo[] mi = typeof(Application).FindMembers(MemberTypes.Constructor |
    MemberTypes.Method,
    BindingFlags.Public | BindingFlags.Static | BindingFlags.NonPublic |
    BindingFlags.Instance | BindingFlags.DeclaredOnly,
    Type.FilterName, "*");
  Console.WriteLine("Number of methods (includes constructors): " + mi.Length);

// Get the set of methods associated with the type
let mi = typeof<Application>.FindMembers(MemberTypes.Constructor |||
             MemberTypes.Method,
             BindingFlags.Public ||| BindingFlags.Static ||| BindingFlags.NonPublic |||
             BindingFlags.Instance ||| BindingFlags.DeclaredOnly,
             Type.FilterName, "*")
printfn $"Number of methods (includes constructors): {mi.Length}"

' Get the set of methods associated with the type
Dim mi As MemberInfo() = _
   GetType(Application).FindMembers( _
   MemberTypes.Constructor Or MemberTypes.Method, _
   BindingFlags.DeclaredOnly, _
   Type.FilterName, "*")
Console.WriteLine("Number of methods (includes constructors): " & _
   mi.Length.ToString())

注解

此字段保存对 方法使用的委托的 FindMembers 引用。 此委托封装的方法采用两个参数：第一个 MemberInfo 是 对象，第二个 Object是 。 方法确定 对象是否 MemberInfo 与 指定的 Object条件匹配。 Object为 分配了一个字符串值，其中可能包括尾随“*”通配符。 仅支持通配符结束字符串匹配。

例如， Object 可以为 分配值“Byte*”。 在这种情况下，当调用委托时FilterName，仅当对象表示MemberInfo的方法的名称以“Byte”开头时，它才会返回 true 。
