Hello,

I have the following while loop. Am trying to test for some values from a split function using c#

However, I dont get any values back in the loop. Whats wrong here

thanks


string[] csvParts = TextBox1.Text.Split(',');
int length = csvParts.Length;

int i = 0;
do
{
    i++;
     
    Label1.Text = length.ToString() 

}
while (i < length);

????

You are just setting the label's Text property to the length of the array returned from the split over and over.

If you want to reference element i in the array, it is

Label1.Text = csvParts[i];

But even then, the label will only contain the value of the last element in the array because you keep overwriting the Text property over and over.

What exactly are you trying to do here???

I know I've said this 10-20 times to you before, but I will say it again: Please consider reading some books on beginning programming to at least get familiar with basic concepts like loops, arrays, setting variables, etc ....

Oh sorry about that.

Basically, what am trying to achieve is to run a loop based on the number of values in the array. So that the loop will process the different values in the array csvParts[i]

However, the loop was not working. So in order to test it, I tried to write out the values of the code in a loop. And increment it with the i++ But i only get the last value.

Hope this is clearer. AS i only get one value back in the loop

[code]int i = 0;
do
{

// get the value from the array

Label1.Text += csvParts[i]+",";

i++;

}

while (i < length -1);[/code]

I got it to work. ta !
