判断字符串，建文件夹....

Question

字符串类似“test/c66c3ef8/c2623bd2/App_global.asax.hmet2dpt.0.cs”
这样的
如果字符串最后面没有"/"则建文件夹“test/c66c3ef8/c2623bd2”
怎么写代码啊？

Answer 1

            string str = "test/c66c3ef8/c2623bd2/App_global.asax.hmet2dpt.0.cs";
            Directory.CreateDirectory(str.Substring(0, str.LastIndexOf("/")));

Answer 2

string str="test/c66c3ef8/c2623bd2/App_global.asax.hmet2dpt.0.cs";
if(str.LastIndexOf("/")<0)
{
  if(!Directory.Exists("~/test/c66c3ef8/c2623bd2/"))
  {
     Directory.CreateDirectory("~/test/c66c3ef8/c2623bd2/");
  }
}

Answer 3

string urlPath=PrePath+"test/c66c3ef8/c2623bd2/App_global.asax.hmet2dpt.0.cs"; //PrePath为你的路径前缀
System.IO.DirectoryInfo diBak = new System.IO.DirectoryInfo(urlPath);
   if (diBak.Exists)
   { return strPreXMLPath;}
   else
   {
     if(urlPath.EndWith(@"/"))
        {diBak.Create();}
     return diBak.FullName;
   }

Answer 4

改改：string str= "test/c66c3ef8/c2623bd2/App_global.asax.hmet2dpt.0.cs";
if(str.LastIndexOf("/") != str.Length - 1)
     Directory.CreateDirectory(str.Substring(0, str.LastIndexOf("/")));
