MethodBuilder.GetParameters 方法

定義

命名空間:
System.Reflection.Emit
組件:
mscorlib.dll
組件:
netstandard.dll

回傳此方法的參數。

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()

傳回

ParameterInfo[]

一組 ParameterInfo 代表方法參數的物件陣列。

例外狀況

NotSupportedException

此方法目前尚未支援。 用 取得 GetMethod(String, BindingFlags, Binder, CallingConventions, Type[], ParameterModifier[]) 方法，並呼叫 GetParameters 返回 MethodInfo的 。

範例

以下範例說明如何利用 GetParameters 來發現傳遞給動態產生方法的參數資訊。


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
