LogicalMethodInfo(MethodInfo) 建構函式

定義

命名空間:

System.Web.Services.Protocols

組件:

System.Web.Services.dll

使用傳入的 LogicalMethodInfo，初始化 MethodInfo 類別的新執行個體。

public:
 LogicalMethodInfo(System::Reflection::MethodInfo ^ methodInfo);

public LogicalMethodInfo (System.Reflection.MethodInfo methodInfo);

new System.Web.Services.Protocols.LogicalMethodInfo : System.Reflection.MethodInfo -> System.Web.Services.Protocols.LogicalMethodInfo

Public Sub New (methodInfo As MethodInfo)

參數

methodInfo

MethodInfo

MethodInfo，要初始化 LogicalMethodInfo 通用於 MethodInfo 的屬性。

例外狀況

InvalidOperationException

methodInfo 參數的 IsStatic 屬性為 true。

-或-

methodInfo 參數的 GetParameters() 方法沒有包含以 LogicalMethodInfo 執行個體所表示方法所需要的所有參數。

範例

#using <System.Web.Services.dll>

using namespace System::Reflection;
using namespace System::Web::Services::Protocols;

public ref class MyService
