Thread.CurrentUICulture 属性

定义

命名空间:

System.Threading

程序集:

System.Threading.Thread.dll

程序集:

netstandard.dll

程序集:

mscorlib.dll

获取或设置资源管理器使用的当前区域性以便在运行时查找区域性特定的资源。

public:
 property System::Globalization::CultureInfo ^ CurrentUICulture { System::Globalization::CultureInfo ^ get(); void set(System::Globalization::CultureInfo ^ value); };

public System.Globalization.CultureInfo CurrentUICulture { get; set; }

member this.CurrentUICulture : System.Globalization.CultureInfo with get, set

Public Property CurrentUICulture As CultureInfo

属性值

CultureInfo

表示当前区域性的对象。

例外

ArgumentNullException

属性设置为 null。

ArgumentException

该属性设置为不能用于定位资源文件的区域性名称。 资源文件名必须仅包含字母、数字、连字符或下划线。

InvalidOperationException

仅限 .NET Core 和 .NET 5 +：不支持从其他线程读取或写入线程的区域性。

示例

下面的示例确定当前线程的 UI 区域性的语言是否为法语。 否则，它会将当前线程的 UI 区域性设置为英语 (美国) 。

using System;
using System.Globalization;
using System.Threading;

public class Example
{
   public static void Main()
   {
      // Change the current culture if the language is not French.
      CultureInfo current = Thread.CurrentThread.CurrentUICulture;
      if (current.TwoLetterISOLanguageName != "fr") {
         CultureInfo newCulture = CultureInfo.CreateSpecificCulture("en-US");
         Thread.CurrentThread.CurrentUICulture = newCulture;
         // Make current UI culture consistent with current culture.
         Thread.CurrentThread.CurrentCulture = newCulture;
      }
      Console.WriteLine("The current UI culture is {0} [{1}]",
                        Thread.CurrentThread.CurrentUICulture.NativeName,
                        Thread.CurrentThread.CurrentUICulture.Name);
      Console.WriteLine("The current culture is {0} [{1}]",
                        Thread.CurrentThread.CurrentUICulture.NativeName,
                        Thread.CurrentThread.CurrentUICulture.Name);
   }
}
// The example displays the following output:
//     The current UI culture is English (United States) [en-US]
//     The current culture is English (United States) [en-US]

Imports System.Globalization
Imports System.Threading

Module Example
   Public Sub Main()
      ' Change the current culture if the language is not French.
      Dim current As CultureInfo = Thread.CurrentThread.CurrentUICulture
      If current.TwoLetterISOLanguageName <> "fr" Then
         Dim newCulture As CultureInfo = CultureInfo.CreateSpecificCulture("en-US")
         Thread.CurrentThread.CurrentUICulture = newCulture
         ' Make current UI culture consistent with current culture.
         Thread.CurrentThread.CurrentCulture = newCulture
      End If
      Console.WriteLine("The current UI culture is {0} [{1}]",
                        Thread.CurrentThread.CurrentUICulture.NativeName,
                        Thread.CurrentThread.CurrentUICulture.Name)
      Console.WriteLine("The current culture is {0} [{1}]",
                        Thread.CurrentThread.CurrentUICulture.NativeName,
                        Thread.CurrentThread.CurrentUICulture.Name)
   End Sub
End Module
' The example displays output like the following:
'     The current UI culture is English (United States) [en-US]
'     The current culture is English (United States) [en-US]

下面的代码示例演示了一个线程语句，该语句允许 Windows 窗体的用户界面显示在 "控制面板" 中设置的区域性。 需要其他代码。

#using <system.dll>
#using <System.Drawing.dll>
#using <system.windows.forms.dll>

using namespace System;
using namespace System::Threading;
using namespace System::Windows::Forms;
ref class UICulture: public Form
{
public:
   UICulture()
   {
      
      // Set the user interface to display in the
      // same culture as that set in Control Panel.
      Thread::CurrentThread->CurrentUICulture = Thread::CurrentThread->CurrentCulture;
      
      // Add additional code.
   }
};


int main()
{
   Application::Run( gcnew UICulture );
}

using System;
using System.Threading;
using System.Windows.Forms;

class UICulture : Form
{
    public UICulture()
    {
        // Set the user interface to display in the
        // same culture as that set in Control Panel.
        Thread.CurrentThread.CurrentUICulture = 
            Thread.CurrentThread.CurrentCulture;

        // Add additional code.
    }

    static void Main()
    {
        Application.Run(new UICulture());
    }
}

Imports System.Threading
Imports System.Windows.Forms

Public Class UICulture : Inherits Form
    Sub New()

        ' Set the user interface to display in the
        ' same culture as that set in Control Panel.
        Thread.CurrentThread.CurrentUICulture = _
            Thread.CurrentThread.CurrentCulture

        ' Add additional code.
    End Sub

    Shared Sub Main()
        Application.Run(New UICulture())
    End Sub
End Class

注解

UI 区域性指定应用程序支持用户输入和输出所需的资源，默认情况下，它与操作系统区域性相同。 请参见 CultureInfo 类以了解区域性名称和标识符、固定、非特定区域性和特定区域性之间的差异，以及区域性信息影响线程和应用程序域的方式。 请参阅 CultureInfo.CurrentUICulture 属性以了解如何确定线程的默认 UI 区域性。

重要

CurrentUICulture与当前线程以外的任何线程一起使用时，属性不能可靠地工作。 在 .NET Framework 中，读取属性是可靠的，但对于除当前线程之外的其他线程，其设置是可靠的。 在 .NET Core 中， InvalidOperationException 如果线程尝试在 CurrentUICulture 另一个线程上读取或写入属性，则会引发。 建议使用 CultureInfo.CurrentUICulture 属性来检索和设置当前区域性。

CultureInfo此属性返回的可能是非特定区域性。 非特定区域性不应与格式设置方法（如 String.Format(IFormatProvider, String, Object[]) 、和）一起使用 DateTime.ToString(String, IFormatProvider) Convert.ToString(Char, IFormatProvider) 。 使用 CultureInfo.CreateSpecificCulture 方法可获取特定区域性，或使用 CurrentCulture 属性。
