According to your title, to get all the index;

 var indexList = Regex.Matches(StrRemoveWrongData, @"<start>").Cast<Match>()
                    .Select(m => m.Index)
                    .ToList();

If your replacement algorightm is more complex than a simple then string you can use the overload of Regex.Replace

int count = 1;
var newstr = Regex.Replace(StrRemoveWrongData, @"<start>", 
                       m => { 
                           //Do some work
                           return String.Format("<child{0}>",count++);
                       }
              );

You can simply do: StrRemoveWrongData = StrRemoveWrongData.Replace(@"<start>", newString);
