Type.FilterName 字段

表示用于名称的区分大小写的成员筛选器。此字段为只读。

**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public Shared ReadOnly FilterName As MemberFilter
用法
Dim value As MemberFilter

value = Type.FilterName

public static readonly MemberFilter FilterName

public:
static initonly MemberFilter^ FilterName

public static final MemberFilter FilterName

public static final var FilterName : MemberFilter

备注

此字段含有对 FindMembers 方法使用的委托的引用。此委托封装的方法使用两个参数：第一个是 MemberInfo 对象，第二个是 Object。此方法确定 MemberInfo 对象是否与 Object 指定的判据相匹配。给 Object 分配了一个字符串值，此字符串值可能包含一个尾部通配符字符“*”。仅支持通配符结尾字符串匹配。

例如，可能分配给 Object 值“Byte*”。在这种情况下，当调用 FilterName 委托时，只有当 MemberInfo 对象表示的方法具有以“Byte”开始的名称，它才返回 true。

示例

下面的代码示例获取与用户定义的 Application 类型关联的方法。

' 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())

// 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
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[] = Application.class.ToType().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
var mi : MemberInfo[] = 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);
