什么是最简单的/典型的方法来创建在C＃中一个空文件/。NET？

我能找到到目前为止，最简单的方法是：

  System.IO.File.WriteAllLines（文件名，新的字符串[0]）;
 

解决方案

只需使用 File.Create 将离开文件打开，这可能是不是你想要的。

您可以使用：

 使用（File.Create（文件名））;
 

这看起来有点奇怪，你要知道。你可以使用大括号来代替：

 使用（File.Create（文件名））{}
 

或者就叫处置直接：

  File.Create（文件名）.Dispose（）;
 

无论哪种方式，如果你打算使用这个在多个地方，你或许应该考虑包装在一个辅助方法，如：

 公共静态无效CreateEmptyFile（字符串文件名）
{
    File.Create（文件名）.Dispose（）;
}
 

请注意，调用处置，而不是直接使用使用声明中并没有真正太大的区别就在这里就我所知道的 - 只有这样，它的可以的有所作为的是，如果线程被调用的夭折而 File.Create 和调用处置。如果那场比赛条件存在，我怀疑这会的也的存在于使用的版本，如果线程被中止，在 File.Create 法，该值返回之前...

What's the simplest/canonical way to create an empty file in C#/.NET?

The simplest way I could find so far is:

System.IO.File.WriteAllLines(filename, new string[0]);

Using just File.Create will leave the file open, which probably isn't what you want.

You could use:

using (File.Create(filename)) ;

That looks slightly odd, mind you. You could use braces instead:

using (File.Create(filename)) {}

Or just call Dispose directly:

File.Create(filename).Dispose();

Either way, if you're going to use this in more than one place you should probably consider wrapping it in a helper method, e.g.

public static void CreateEmptyFile(string filename)
{
    File.Create(filename).Dispose();
}

Note that calling Dispose directly instead of using a using statement doesn't really make much difference here as far as I can tell - the only way it could make a difference is if the thread were aborted between the call to File.Create and the call to Dispose. If that race condition exists, I suspect it would also exist in the using version, if the thread were aborted at the very end of the File.Create method, just before the value was returned...
