FieldInfo.IsPinvokeImpl 属性

定义

命名空间:

System.Reflection

程序集:

System.Runtime.dll

Source:

FieldInfo.cs

获取一个值，该值指示是否已在 FieldAttributes 中设置相应的 PinvokeImpl 特性。

public:
 property bool IsPinvokeImpl { bool get(); };

public bool IsPinvokeImpl { get; }

member this.IsPinvokeImpl : bool

Public ReadOnly Property IsPinvokeImpl As Boolean

属性值

Boolean

如果在 FieldAttributes 中设置了 true 特性，则为 PinvokeImpl；否则为 false。

示例

以下示例创建一个类，并显示字段的名称、字段和 IsPinvokeImpl 属性值。

using namespace System;
using namespace System::Reflection;

public ref class Fieldinfo_IsPinvoke
{
public:
   String^ myField;
   Fieldinfo_IsPinvoke()
   {
      myField = "A public field";
   }
};

int main()
{
   Fieldinfo_IsPinvoke^ myObject = gcnew Fieldinfo_IsPinvoke;

   // Get the Type and FieldInfo.
   Type^ myType1 = Fieldinfo_IsPinvoke::typeid;
   FieldInfo^ myFieldInfo = myType1->GetField( "myField", static_cast<BindingFlags>(BindingFlags::Public | BindingFlags::Instance) );

   // Display the name, field and the PInvokeImpl attribute for the field.
   Console::Write( "\n Name of class: {0}", myType1->FullName );
   Console::Write( "\n Value of field: {0}", myFieldInfo->GetValue( myObject ) );
   Console::Write( "\n IsPinvokeImpl: {0}", myFieldInfo->IsPinvokeImpl );
}

using System;
using System.Reflection;

public class Fieldinfo_IsPinvoke
{
    public string myField = "A public field";

    public static void Main()
    {
        Fieldinfo_IsPinvoke myObject = new Fieldinfo_IsPinvoke();

        // Get the Type and FieldInfo.
        Type myType1 = typeof(Fieldinfo_IsPinvoke);
        FieldInfo myFieldInfo = myType1.GetField("myField",
            BindingFlags.Public|BindingFlags.Instance);

        // Display the name, field and the PInvokeImpl attribute for the field.
        Console.Write("\n Name of class: {0}", myType1.FullName);
        Console.Write("\n Value of field: {0}", myFieldInfo.GetValue(myObject));
        Console.Write("\n IsPinvokeImpl: {0}",
            myFieldInfo.IsPinvokeImpl );
    }
}

Imports System.Reflection

Public Class Fieldinfo_IsPinvoke
    Public myField As String = "A public field"

    Public Shared Sub Main()
        Dim myObject As New Fieldinfo_IsPinvoke()

        ' Get the Type and FieldInfo.
        Dim myType1 As Type = GetType(Fieldinfo_IsPinvoke)
        Dim myFieldInfo As FieldInfo = myType1.GetField("myField", _
           BindingFlags.Public Or BindingFlags.Instance)

        ' Display the name, field and the PInvokeImpl attribute for the field.
        Console.Write(ControlChars.NewLine & "Name of class: {0}", _
                                         myType1.FullName)
        Console.Write(ControlChars.NewLine & "Value of field: {0}", _
                                         myFieldInfo.GetValue(myObject))
        Console.Write(ControlChars.NewLine & "IsPinvokeImpl: {0}", _
                                         myFieldInfo.IsPinvokeImpl)
    End Sub
End Class
