Type.IsAnsiClass 屬性

定義

取得值,指出是否為 AnsiClass 選取字串格式屬性 TypeGets a value indicating whether the string format attribute AnsiClass is selected for the Type.

public:
 property bool IsAnsiClass { bool get(); };
public bool IsAnsiClass { get; }
member this.IsAnsiClass : bool
Public ReadOnly Property IsAnsiClass As Boolean

屬性值

如果為 true 選取字串格式屬性 AnsiClass,則為 Type,否則為 falsetrue if the string format attribute AnsiClass is selected for the Type; otherwise, false.

範例

下列範例會取得欄位資訊,並檢查 AnsiClass 屬性。The following example gets the field information and checks for the AnsiClass attribute.

using namespace System;
using namespace System::Reflection;
public ref class MyClass
{
protected:
   String^ myField;

public:
   MyClass()
   {
      myField =  "A sample protected field";
   }
};

int main()
{
   try
   {
      MyClass^ myObject = gcnew MyClass;
      
      // Get the type of the 'MyClass'.
      Type^ myType = MyClass::typeid;
      
      // Get the field information and the attributes associated with MyClass.
      FieldInfo^ myFieldInfo = myType->GetField( "myField", static_cast<BindingFlags>(BindingFlags::NonPublic | BindingFlags::Instance) );
      Console::WriteLine( "\nChecking for the AnsiClass attribute for a field.\n" );
      
      // Get and display the name, field, and the AnsiClass attribute.
      Console::WriteLine( "Name of Class: {0} \nValue of Field: {1} \nIsAnsiClass = {2}", myType->FullName, myFieldInfo->GetValue( myObject ), myType->IsAnsiClass );
   }
   catch ( Exception^ e ) 
   {
      Console::WriteLine( "Exception: {0}", e->Message );
   }
}
using System;
using System.Reflection;
public class MyClass
{
    protected string myField = "A sample protected field." ;
}
public class MyType_IsAnsiClass
{
    public static void Main()
    {
        try
        {
            MyClass myObject = new MyClass();
            // Get the type of the 'MyClass'.
            Type myType = typeof(MyClass);
            // Get the field information and the attributes associated with MyClass.
            FieldInfo myFieldInfo = myType.GetField("myField", BindingFlags.NonPublic|BindingFlags.Instance);
            Console.WriteLine( "\nChecking for the AnsiClass attribute for a field.\n"); 
            // Get and display the name, field, and the AnsiClass attribute.
            Console.WriteLine("Name of Class: {0} \nValue of Field: {1} \nIsAnsiClass = {2}", myType.FullName, myFieldInfo.GetValue(myObject), myType.IsAnsiClass);
        }
        catch(Exception e)
        {
            Console.WriteLine("Exception: {0}",e.Message);
        }
    }
}
Imports System.Reflection

Public Class MyClass1
    Protected myField As String = "A sample protected field."
End Class
Public Class MyType_IsAnsiClass
    Public Shared Sub Main()
        Try
            Dim myObject As New MyClass1()
            ' Get the type of MyClass1.
            Dim myType As Type = GetType(MyClass1)
            ' Get the field information and the attributes associated with MyClass1.
            Dim myFieldInfo As FieldInfo = myType.GetField("myField", BindingFlags.NonPublic Or BindingFlags.Instance)

            Console.WriteLine(ControlChars.NewLine + "Checking for AnsiClass attribute for a field." + ControlChars.NewLine)
            ' Get and display the name, field, and the AnsiClass attribute.
            Console.WriteLine("Name of Class: {0} " + ControlChars.NewLine + "Value of Field: {1} " + ControlChars.NewLine + "IsAnsiClass = {2}", myType.FullName, myFieldInfo.GetValue(myObject), myType.IsAnsiClass)
        Catch e As Exception
            Console.WriteLine("Exception: {0}", e.Message.ToString())
        End Try
    End Sub
End Class

備註

StringFormatMask 會選取字串格式屬性。The StringFormatMask selects the string format attributes. 字串格式屬性會藉由定義應該如何解讀字串,來增強互通性。The string format attributes enhance interoperability by defining how strings should be interpreted.

如果目前 Type 代表泛型型別,這個屬性就會與用來建立型別的泛型型別定義有關。If the current Type represents a generic type, this property pertains to the generic type definition from which the type was constructed. 例如,如果目前的 Type 表示 Visual Basic 中的 MyGenericType<int>MyGenericType(Of Integer)),則這個屬性的值是由 MyGenericType<T>所決定。For example, if the current Type represents MyGenericType<int> (MyGenericType(Of Integer) in Visual Basic), the value of this property is determined by MyGenericType<T>.

如果目前的 Type 表示泛型型別的型別參數,則這個屬性一律會傳回 falseIf the current Type represents a type parameter of a generic type, this property always returns false.
