    Yes, its called the .Substring method of your string variable or .Text property of some control.


    VB Code:
    1. Dim strIP As String
    2. Dim strStart As Integer
    3. Dim strEnd As Integer
    4. Dim strString As String = "FRQ [ 859.3125]"
    5. strStart = strString.IndexOf("[") + 1
    6. strEnd = strString.LastIndexOf("]") - 1
    7. strIP = strString.Substring(strStart, strEnd - strStart)
    8. MessageBox.Show(strIP.Trim) '859.3125

    Re: Mid function in c#.net or equivalent

    As RobDob pointed out, the Mid function equivalent is easy in .NET, but if you were thinking of the Mid statement (e.g., Mid(x, 2, 3) = "abc"), that is *extremely complex* to generalize to a pure .NET solution.

    For example:
    Mid(x, 2) = "abc"

    is equivalent to:
    x = x.PadRight(x.Length + ("abc").Length).Remove(1, ("abc").Length).Insert(1, "abc").Substring(0, x.Length);

    You see my point - you would obviously want to write your own Mid statement.

    There is none, but it is quite simple to write one using Substring

    public static class strMid
    {
    public static string Mid(string s, int a, int b)
    {
    string temp = s.Substring(a - 1, b);
    return temp;
    }

    }
