Hi Rakib Abmed,

According to your description, I have made a sample here. I suggest you to use substring() method to get the part of the line. Substring() could get the part of the string,in this case,you could .substring(0,5) to get the first six digits of the string,then you could judge the string you get is "ORDINE" or "ordine"or "other". Here is the demo , I hope it could help you.

aspx:

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
  
    <title></title>
   
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
            <asp:Button ID="Button1" runat="server" Text="check" OnClick="Button1_Click" />
        </div>
    </form>
</body>
</html>

code behind:

public partial class ordine : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            var str = TextBox1.Text;
            if (str.Length >= 6)// make sure the text is longer than 6 size. 
            {
                string str1 = TextBox1.Text.Substring(0, 5); // get the first six digits of text
                if (str == "ORDINE")
                {
                    Response.Write("start with capital ordine ");

                }
                else if (str == "ordine")
                {

                    Response.Write("start with lowercase ordine");
                }
                else
                {
                    Response.Write("is not capital or lowercase");

                }



            }
            else
            {

                Response.Write("is not capital or lowercase");
            }
           
        }
    }
