Question

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#.

Answer 1

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);
}
