LogicalMethodInfo.IsBeginMethod(MethodInfo) 方法

定义

命名空间:

System.Web.Services.Protocols

程序集:

System.Web.Services.dll

返回一个值，该值指示传入的方法是否表示异步调用的 Begin 方法。

public:
 static bool IsBeginMethod(System::Reflection::MethodInfo ^ methodInfo);

public:
 static bool IsBeginMethod(System::Reflection::MethodInfo ^ method_info);

public static bool IsBeginMethod (System.Reflection.MethodInfo methodInfo);

public static bool IsBeginMethod (System.Reflection.MethodInfo method_info);

static member IsBeginMethod : System.Reflection.MethodInfo -> bool

static member IsBeginMethod : System.Reflection.MethodInfo -> bool

Public Shared Function IsBeginMethod (methodInfo As MethodInfo) As Boolean

Public Shared Function IsBeginMethod (method_info As MethodInfo) As Boolean

参数

methodInfomethod_info

MethodInfo

可能是异步调用的 Begin 方法的 MethodInfo。

返回

Boolean

如果 methodInfo 参数为异步调用的 true 方法，则为 Begin；否则为 false。
