我已经写了这个小方法来实现的SUBJ的目标。但是，有这样做的更有效的（简单）的方式？我希望这可以帮助别人谁将会搜索这个像我一样。

I've wrote this little method to achieve the goal in the subj., however, is there more efficient (simpler) way of doing this? I hope this can help somebody who will search for this like I did.

var fileName = new System.Text.StringBuilder();
fileName.Append("*Bad/ :, Filename,? ");
// get rid of invalid chars
while (fileName.ToString().IndexOfAny(System.IO.Path.GetInvalidFileNameChars()) > -1)
{
    fileName = fileName.Remove(fileName.ToString().IndexOfAny(System.IO.Path.GetInvalidFileNameChars()), 1);
}

推荐答案

请尝试以下

public string MakeValidFileName(string name) {
  var builder = new StringBuilder();
  var invalid = System.IO.Path.GetInvalidFileNameChars();
  foreach ( var cur in name ) {
    if ( !invalid.Contains(cur) ) {
      builder.Append(cur);
    }
  }
  return builder.ToString();
}
