Question

How to replace the same occurrences in Excel with a different string?

The problem I have with Excel.Range.Replace is that the method replaces all occurrences in a single call. For example if I do the following:

for (int i = 0; i < myNum; i++)
{
    myRange.Replace("foo", i.ToString());
}

Then all “foo” will be replaced with 0 instead of 1, 2 ,3 ...

void ReplaceFoosWithNumbers()
{
    int i;
    Range c;
    string firstAddress;

    Range rangeToSearchIn =  Worksheets(1).Range("a1:a5");
    Set c = rangeToSearchIn.Find("Foo", LookIn:=xlValues)
    if (c != null) 
    {
        firstAddress = c.Address
        while (true)
        {
            c.Value = i
            i = i + 1
            c = rangeToSearchIn.FindNext(c)
            if (c == null)
                break;
        }
    }
}
