Type.IsAnsiClass Type.IsAnsiClass Type.IsAnsiClass Type.IsAnsiClass Property

定义

获取一个值,该值指示是否为 AnsiClass 选择了字符串格式属性 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

属性值

如果为 true 选择了字符串格式属性 AnsiClass,则为 Type;否则为 falsetrue if the string format attribute AnsiClass is selected for the Type; otherwise, false.

实现

示例

下面的示例获取字段信息并检查AnsiClass特性。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 'MyClass1
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 'Main
End Class 'MyType_IsAnsiClass

注解

StringFormatMask选择字符串格式特性。The StringFormatMask selects the string format attributes. 字符串格式特性通过定义应如何解释字符串来增强互操作性。The string format attributes enhance interoperability by defining how strings should be interpreted.

如果当前Type表示泛型类型,则此属性适用于构造该类型的泛型类型定义。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Type当前表示MyGenericType<int>MyGenericType(Of Integer)在 Visual Basic 中),则此属性的值由确定MyGenericType<T>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>.

如果当前Type表示泛型类型的类型参数,则此属性始终返回falseIf the current Type represents a type parameter of a generic type, this property always returns false.
