MethodBuilder.GetParameters 方法

定义

命名空间:

System.Reflection.Emit

程序集:

System.Reflection.Emit.dll

返回此方法的参数。

public:
 override cli::array <System::Reflection::ParameterInfo ^> ^ GetParameters();

public override System.Reflection.ParameterInfo[] GetParameters ();

override this.GetParameters : unit -> System.Reflection.ParameterInfo[]

Public Overrides Function GetParameters () As ParameterInfo()

返回

ParameterInfo[]

表示此方法的参数的 ParameterInfo 对象数组。

例外

NotSupportedException

目前尚不支持此方法。 使用 GetMethod(String, BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) 检索此方法，并在返回的 MethodInfo 上调用 GetParameters。

示例

下面的代码示例演示了如何使用 GetParameters 来发现有关传递给动态生成方法的参数的信息。

TypeBuilder^ myType1 = myModBuilder->DefineType( "MyMathFunctions", TypeAttributes::Public );
array<Type^>^temp0 = {Type::GetType( "System.Int32&" ),int::typeid};
MethodBuilder^ myMthdBuilder = myType1->DefineMethod( "AddToRefValue", MethodAttributes::Public, void::typeid, temp0 );
ParameterBuilder^ myParam1 = myMthdBuilder->DefineParameter( 1, ParameterAttributes::Out, "thePool" );
ParameterBuilder^ myParam2 = myMthdBuilder->DefineParameter( 2, ParameterAttributes::In, "addMeToPool" );

// Create body via ILGenerator here, and complete the type.
array<ParameterInfo^>^myParams = myMthdBuilder->GetParameters();
Console::WriteLine( "Method: {0}", myMthdBuilder->Name );

for each (ParameterInfo^ myParam in myParams)
{
   Console::WriteLine("------- Parameter: {0} {1} at pos {2}, with attribute {3}", 
      myParam->ParameterType, myParam->Name, myParam->Position,
            myParam->Attributes.ToString());
}

TypeBuilder myType1 = myModBuilder.DefineType("MyMathFunctions",
                TypeAttributes.Public);

MethodBuilder myMthdBuilder = myType1.DefineMethod("AddToRefValue",
                MethodAttributes.Public,
                typeof(void),
                new Type[] { Type.GetType("System.Int32&"),
                         typeof(int) });
ParameterBuilder myParam1 = myMthdBuilder.DefineParameter(1,
                ParameterAttributes.Out,
                "thePool");
ParameterBuilder myParam2 = myMthdBuilder.DefineParameter(2,
                ParameterAttributes.In,
                "addMeToPool");

// Create body via ILGenerator here, and complete the type.

ParameterInfo[] myParams = myMthdBuilder.GetParameters();

Console.WriteLine("Method: {0}", myMthdBuilder.Name);

foreach (ParameterInfo myParam in myParams)
    {
   Console.WriteLine("------- Parameter: {0} {1} at pos {2}, with attribute {3}",
             myParam.ParameterType, myParam.Name, myParam.Position,
             myParam.Attributes.ToString());
    }

Dim myType1 As TypeBuilder = myModBuilder.DefineType("MyMathFunctions", _
                      TypeAttributes.Public)

Dim myMthdBuilder As MethodBuilder = myType1.DefineMethod("AddToRefValue", _
          MethodAttributes.Public, Nothing, _
          New Type() {Type.GetType("System.Int32&"), GetType(Integer)})

Dim myParam1 As ParameterBuilder = myMthdBuilder.DefineParameter(1, _
                  ParameterAttributes.Out, "thePool")

Dim myParam2 As ParameterBuilder = myMthdBuilder.DefineParameter(2, _
                  ParameterAttributes.In, "addMeToPool")

' Create body via ILGenerator here, and complete the type.

Dim myParams As ParameterInfo() = myMthdBuilder.GetParameters()

Console.WriteLine("Method: {0}", myMthdBuilder.Name)

Dim myParam As ParameterInfo
For Each myParam In  myParams
   Console.WriteLine("------- Parameter: {0} {1} at pos {2}, with attribute {3}", _
          myParam.ParameterType, myParam.Name, myParam.Position, _
          myParam.Attributes.ToString())
Next myParam
