定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
获取一个值,该值指示是否为 AnsiClass
选择了字符串格式属性 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 false
。
实现
示例
以下示例获取字段信息并检查 AnsiClass
属性。
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);
}
}
}
open System.Reflection

try
let myObject = MyClass()
// Get the type of the 'MyClass'.
let myType = typeof<MyClass>
// Get the field information and the attributes associated with MyClass.
let myFieldInfo = myType.GetField("myField", BindingFlags.NonPublic ||| BindingFlags.Instance)
printfn "\nChecking for the AnsiClass attribute for a field.\n"
// Get and display the name, field, and the AnsiClass attribute.

with e ->
printfn $"Exception: {e.Message}"

End Class
Public Class MyType_IsAnsiClass

' 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
注解
选择 StringFormatMask 字符串格式属性。 字符串格式属性通过定义应如何解释字符串来增强互操作性。
如果当前 Type 表示泛型类型,则此属性与构造该类型的泛型类型定义相关。 例如,如果当前 Type 表示 MyGenericType<int>
Visual Basic) MyGenericType(Of Integer)
中的 (,则此属性的值由 MyGenericType<T>
确定。
如果当前 Type 表示泛型类型的类型参数,则此属性始终返回 false
。
