Type.FilterNameIgnoreCase 字段
表示用于名称的不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 FilterNameIgnoreCase As MemberFilter
用法
Dim value As MemberFilter
value = Type.FilterNameIgnoreCase
public static readonly MemberFilter FilterNameIgnoreCase
public:
static initonly MemberFilter^ FilterNameIgnoreCase
public static final MemberFilter FilterNameIgnoreCase
public static final var FilterNameIgnoreCase : 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，它才返回真，不区分大小写。
示例
下面的示例获取 MemberFilter 委托，将其作为参数传递给 FindMembers 方法，然后显示这些方法及 String 类的以字母“c”或“C”开头的属性。
