如何以正确的方式捕获路径/字符串？

Question

我正在寻找捕获路径不以Path1开头的可能性的最佳实践。 像path这样的东西等于“C：\\ test \ yes”而a.Setting.PathSettings.Path1等于“C：\ test \”。

如何避免失败？

String path1 = "C:\test\yes";
String path2 = "C:\test\yes";

pathDir = new FileInfo("C:\\\test\yes\test.txt").Directory.FullName;
pathDir = pathDir.Replace(a.Setting.PathSettings.Path1, a.Setting.PathSettings.Path2);

亲切的问候

Answer 1

您可以使用String.StartsWith

进行检查

if(path.StartsWith(a.Settings.PathSettings.Path1)
{
  path=path.Replace(a.Setting.PathSettings.Path1, a.Setting.PathSettings.Path2);
}
