Build a Generic function to compare values of all DataTypes in C# .Net

There is no latest way you need to use the same olf TryParse to determine what type of data you have and then based on that convert and do comparison

I have created a small sample that does comparision for integer and date in dd/MM/yyyy format

private bool Compare(string text1, string text2)
    {
        int number1;
        int number2;
        DateTime date1;
        DateTime date2;
        bool result = false;
        if (int.TryParse(text1, out number1) && int.TryParse(text1, out number2))
        {
            //It is an integer
             result = number1 > number2;
        }
        else if (DateTime.TryParse(text1, new CultureInfo("en-GB"), DateTimeStyles.None, out date1) && DateTime.TryParse(text2, new CultureInfo("en-GB"), DateTimeStyles.None, out date2))
        {
            //It is a Date in dd/MM/yyyy format
             result = date1 > date2;
        }
        return result;
    }

Namespace

using System.Globalization;

Example usage

TextBox1.Text = "12";
        TextBox2.Text = "15";
        bool result = Compare(TextBox1.Text, TextBox2.Text);

        TextBox1.Text = "12/09/2014";
        TextBox2.Text = "15/08/2014";
        result = Compare(TextBox1.Text, TextBox2.Text);

        Label Label1 = new Label();
        string s = "This is a very longgggggggggggggg text";
        Label1.Text = s.Length > 10 ? s.Substring(0, 10) : s;
