Thread.CurrentUICulture Property

Gets or sets the current culture used by the Resource Manager to look up culture-specific resources at run time.

Namespace:  System.Threading
Assembly:  mscorlib (in mscorlib.dll)

public CultureInfo CurrentUICulture { get; set; }

Property Value

Type: System.Globalization.CultureInfo
An object that represents the current culture.

ExceptionCondition
ArgumentNullException

The property is set to null.

ArgumentException

The property is set to a culture name that cannot be used to locate a resource file. Resource filenames must include only letters, numbers, hyphens or underscores.

The UI culture specifies the resources an application needs to support user input and output, and by default is the same as the operating system culture. See the CultureInfo class to learn about culture names and identifiers, the differences between invariant, neutral, and specific cultures, and the way culture information affects threads and application domains. See the CultureInfo.CurrentUICulture property to learn how a thread's default UI culture is determined.

The CultureInfo returned by this property can be a neutral culture. Neutral cultures should not be used with formatting methods such as String.Format(IFormatProvider, String, Object[]), DateTime.ToString(String, IFormatProvider), and Convert.ToString(Char, IFormatProvider). Use the CultureInfo.CreateSpecificCulture method to get a specific culture, or use the CurrentCulture property.

NoteNote

The CultureInfo.CreateSpecificCulture method throws ArgumentException for the neutral cultures "zh-Hant" ("zh-CHT") and "zh-Hans" ("zh-CHS").

The following code example shows the threading statement that allows the user interface of a Windows Forms to display in the culture that is set in Control Panel. Additional code is needed.


// Compile with option /t:winexe.

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.
    }

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