Question

http://www.test.com/test.aspx?testinfo=&|&

I am trying to replace & with values from a table. I got name and age as two paramaters that I need to substitue and get url like this:

http://www.test.com/test.aspx?testinfo=name|age

If I have 3 string parameters to be replaced for a url:

http://www.test.com/test.aspx?testinfo=&|&

Viz name, age, address for the above url:

http://www.test.com/test.aspx?testinfo=name|age|address

string URL=string.Empty;
URL=http://www.test.com/test.aspx?testinfo=&|&;
//in this case fieldsCount is 2, ie. name and age
for(int i=0; i<fieldsCount.Length-1;i++)
{
      URL.Replace("*","name");
}

How do I add “age” so that I get ? any inputs will be helpful.

I think this is what you want,

    List<string> keys = new List<string>() { "name", "age", "param3" };
    string url = "http://www.test.com/test.aspx?testinfo=&|&;";
    Regex reg = new Regex("&");
    int count = url.Count(p => p == '&');

    for (int i = 0; i < count; i++)
    {
        if (i >= keys.Count)
            break;
        url = reg.Replace(url, keys[i], 1);
    }
