Hi Venkatzeus,

Hi,

I have a string where in the data is in the format of http://server/sitename/folder1/folder2/123_0.0 . I am using C#.

I would like to remove the last string and get the result in the format of "http://server/sitename/folder1/folder2/".

I have tried using substring and index as below, but the expected output is not shown. How to fix this? Thanks

posturl = posturl.Substring(posturl.IndexOf("\\") + 1 );

Using the Uri class to resolve Uri, you can use the Segment property to access all segments and rebuild the Uri without the last segment.

var myString = "http://server/sitename/folder1/folder2/123_0.0";

var uri = new Uri(myString);

var noLastSegment = string.Format("{0}://{1}", uri.Scheme, uri.Authority);

for (int i = 0; i < uri.Segments.Length - 1; i++)
{
   noLastSegment += uri.Segments[i];
}

noLastSegment = noLastSegment.Trim("/".ToCharArray()); // remove trailing `/`
Console.WriteLine(noLastSegment);

Regards,
