How to solve array out of bound exception in asp.net?

Question

0.00/5 (No votes)

See more:

If I give only F_Name or only F_Name & L_Name, than I get following error:

Index was outside the bounds of the array.

My code is

C#

string[] names = Receiver_Id_TextBox1.Text.Split;
F_Name = names[0];
M_Name = names[1];
L_Name = names[2];
cmd.CommandText = "SELECT PROFILE_ID, FIRST_NAME,MIDDLE_NAME,LAST_NAME FROM     DSProfile.HDR_PROFILE WHERE FIRST_NAME='" + F_Name + "'OR MIDDLE_NAME='" + M_Name + "' OR LAST_NAME= '" + L_Name + "' ";
string id = Convert.ToString(cmd.ExecuteScalar());

I want to give input either F_Name, or F_Name & L_Name, or F_Name, M_Name & L_Name.

What should i do to remove exception?

Solution 2

Try following code:-

C#

string[] names = Receiver_Id_TextBox1.Text.Split;
int arraySize = names.Lenth;
switch(arraySize)
{
   Case 1: //assign F_name;
    Break;
   Case 2: //assign F name & Lname
    Break
   case 3: // assign all three
    Break;
}

Hi,

Have you debugged and checked what value are you getting in the names array actually?
Looking at the code it seems that names array will be having the value of Receiver_Id_TextBox1.
Debug and see whether are you getting enough values to actually initialize all of your name variables.
