Split and replace string

I have a string in a format:

string path="/fm/Templates/testTemplate/css/article.jpg";

I want to split this with second '/' and replace with '/' to '\\' want a result like this.

string newPath="\\Templates\\testTemplate\\css\\article.jpg";

My path is dynamic created so folder hierarchy is not fixed. What is the best way to do this.May I split first string path with / and go to loop to re-concate this and repalce with '/' to '\\' or there any easy way I am missing.

You may create a new string after removing the first item from the path. The following will give you the desired result. It may be optimized.

You can try:

  • Split the string on char / and remove empty entries.
  • Get a new array after disregarding the first item from the split array
  • Use string.Join to create the new string with \\ as separator.

Here is the code:

string path = "/fm/Templates/testTemplate/css/article.jpg";
string[] temp = path.Split("/".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
var newTemp = temp.AsEnumerable().Where((r, index) => index > 0);
string newPath2 = string.Join("\\", newTemp);

Try with this:

public static int nthOccurrence(String str, char c, int n)
{
    int pos = str.IndexOf(c, 0);
    while (n-- > 0 && pos != -1)
        pos = str.IndexOf(c, pos + 1);
    return pos;
}    

string path = "/fm/Templates/testTemplate/css/article.jpg";

int index = nthOccurrence(path, '/', 1);
string newpath = path.Substring(index).Replace("/", "\\");

OUTPUT: "\\Templates\\testTemplate\\css\\article.jpg"

Is your string manipulation really so time critical that you need to do everything at once? It's much easier just to break it down into parts:

// First remove the leading /../ section:
path = Regex.Replace("^/[^/]*/", "", path);

// Then replace any remaining /s with \s:
path = path.Replace("/", "\\");

string path = "/fm/Templates/testTemplate/css/article.jpg";
path = path.Substring(path.IndexOf('/', 1)).Replace("/", "\\\\");

Try this,

string path = "/fm/Templates/testTemplate/css/article.jpg";
string[] oPath = path.Split('/');
string newPath = @"\\" + string.Join(@"\\", oPath, 2, oPath.Length - 2);
Console.WriteLine(newPath);

You can use the following code.

string path="/fm/Templates/testTemplate/css/article.jpg"; 
string newpath = path.Replace("/fm", string.Empty).Replace("/","\\");

Thanks

If you're working with individual segments of your path (and not just replacing the direction of the slashes), the System.Uri class will help (.Segments property).

Eg from MSDN

Uri uriAddress1 = new Uri("http://www.contoso.com/title/index.htm");
Console.WriteLine("The parts are {0}, {1}, {2}", uriAddress1.Segments[0], uriAddress1.Segments[1], uriAddress1.Segments[2]);

Can't you just use String.Replace?
