String split operations in C#

I have a string say string s ="C:\\Data" , I have an array which contains some strings containg "C:\Data" in the beginning i.e. string[] arr = new {"C:\\Data\abc.xml","C:\\Data\Test\hello.cs"};.

I have to remove the string "C:\Data" from each entry and have to combine it with another string say string fixed = "D:\\Data".

What is the best way to do it, please help as I am a new programmer in C#.

String.Replace is perhaps not what you need, as it would replace all the occurrences of C:\Data in your string, whereas you need only that at the beginning.

I would suggest the following:

string s ="C:\\Data";
string s1 = "D:\\Data";
for (int i = 0; i < arr.Count; i++)
{
    if (arr[i].StartsWith(s))
        arr[i] = s1 + arr[i].Remove(s.Length);
}

Combining LINQ and string.Replace():

arr.Select(s => s.Replace("C:\\Data", "D:\\Data").ToArray();

for (var i=0; i < arr.Length; i++)
  arr[i] = arr[i].Replace("C:\\Data", "D:\\Data");

String.replace would take care of that pretty easily.

If you're sure that all of the elements in your array begin with "C:\Data", then it's pretty simple:

for(int i = 0; i<arr.Length; i++)
{
   arr[i] = arr[i].Replace("C:\\Data" , "D:\\Data");
}

You could use LINQ and do

String[] newStrings = arr.Select(oldString => fixed + oldString.Replace(s, ""))
                         .ToArray()

Note that fixed is a keyword in c# and therefore a bad choice for a variable name.
