Question

我读了csv文件，列与逗号分开。在某些文化中，分隔符是点，因此我决定将当前文化更改为＆＃34; en-US＆＃34;，他们使用逗号作为分隔符。但是当我完成某些操作后，我需要返回用户使用的文化。但我不能。

如何返回用户使用的当前文化？

Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("en-US");
// do something 
CultureInfo ci = CultureInfo.CurrentCulture;
var a = ci.DisplayName;

继续是＆＃34; en-US＆＃34;

Answer 1

只需保存，然后恢复：

var saved = Thread.CurrentThread.CurrentCulture;

try {
  Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("en-US");
  // do something 
finally {
  Thread.CurrentThread.CurrentCulture = saved;
}

另一个（有点异国情调）可能性是在特别设计的类中隐藏逻辑：

public sealed class CurrentCulture: IDisposable {
  private CultureInfo m_Saved;

  public CurrentCulture(CultureInfo info) {
    //TODO: validate info
    m_Saved = Thread.CurrentThread.CurrentCulture;
    Thread.CurrentThread.CurrentCulture = info;
  }

  public CurrentCulture(String name) :
    this(new CultureInfo(name)) {
  }

  public void Dispose() {
    if (m_Saved != null) {
      Thread.CurrentThread.CurrentCulture = m_Saved;
      m_Saved = null;
    }
  }
}

...

using (var c = new CurrentCulture("en-US")) {
  // do something 
}

Answer 2

//Save your current culture;
var myCurrentCulture = Thread.CurrentThread.CurrentCulture;

//Adjust the culture
Thread.CurrentThread.CurrentCulture = CultureInfo.GetCultureInfo("en-US");

//Set it back
Thread.CurrentThread.CurrentCulture = myCurrentCulture;

CultureInfo ci = CultureInfo.CurrentCulture;
var a = ci.DisplayName;
