How can I change the CurrentCulture of the entire process (not just current thread) in .Net?

问题

I have a situation where I need to set my process' locale to en-US.

I know how to do this for the current thread:

System.Threading.Thread.CurrentThread.CurrentCulture = 
     System.Globalization.CultureInfo.CreateSpecificCulture("en-US");

But my application uses BackgroundWorkers to do some processing, and the locale for these worker threads seems not to be affected by the above change to their spawning main-thread.

So how can I set the locale for all the threads in my application without setting it in each one manually?

回答1:

You'll have to change the operating system locale if you want to do that. For what reason do you want BackgroundWorkers to run in en-US?

You should have your business layer running in an invariant culture, and only have a specific culture for the end user's UI.

If you are using the BackgroundWorker component, and have to do this you could try something like this in the DoWork method:

// In DoWork
System.Globalization.CultureInfo before = System.Threading.Thread.CurrentThread.CurrentCulture;
try

{
    System.Threading.Thread.CurrentThread.CurrentCulture = 
        new System.Globalization.CultureInfo("en-US");
 // Proceed with specific code
}

finally
{
    System.Threading.Thread.CurrentThread.CurrentUICulture = before;
}

With 4.0, you will need to manage this yourself by setting the culture for each thread. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.

Use this:

worker.RunWorkerAsync(Thread.CurrentThread.CurrentCulture.LCID);//Pass the LCID as argument

after on do work make this:

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(int.Parse(e.Argument.ToString()));

We use helper class for BackgroudWorker like this:

public static class BackgroundWorkerHelper
{
public static void RunInBackground(Action doWorkAction, Action completedAction, CultureInfo cultureInfo)
    {
        var worker = new BackgroundWorker();
        worker.DoWork += (_, args) =>
        {
            System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;
            System.Threading.Thread.CurrentThread.CurrentUICulture = cultureInfo;
            doWorkAction.Invoke();
        };
        worker.RunWorkerCompleted += (_, args) =>
        {
            System.Threading.Thread.CurrentThread.CurrentCulture = cultureInfo;
            System.Threading.Thread.CurrentThread.CurrentUICulture = cultureInfo;
            completedAction.Invoke();
        };

        worker.RunWorkerAsync();
    }
}

Example usage:

BackgroundWorkerHelper.RunInBackground(() => { Work(); }, () => { AfterWork(); },Thread.CurrentThread.CurrentCulture);
