 Posted: Wed Apr 16, 2008 1:42 pm Post subject: Question about C# |
 |
|
This is my question: I have label1 with number 1, label2 with number 1 and label3 in my form. The thing i want to do is that label3 shows how much is label1.text + label2.text so label3 should show 2 becouse the text of label1 is 1 and text of label 2 is 1. I tried google but didn't found answer. I also tried microsofts developer center but didn't found answer.
P.S
i tried:
| Code: | int i = label1.text
int s = label2.text
label3.text = i+s |
but i got error that type string cannot be converted to type int

| As far as i know, labels store their values in a string format, and since you want integer to add the two numbers together, you will need to convert the labels, dont know how you do this in C#...

There are several ways in getting the number from text. Here is an example
| Code: |
int i = int.Parse(label1.Text);
int s = int.Parse(label2.Text);
int total = i + s;
label3.Text = total.ToString();
|
You could also use Convert.ToInt32().

Ok, I'm assuming that what you want to do is take the number of characters in labels 1 and 2, and show that in label 3.
| Code: |
int length = label1.Text.Length + label2.Text.Length;
label3.Text = length.ToString();

What killersamurai said was correct (samuri25404, he wants to add the values from label1 and label2, not the length - I could be wrong though).
Unless you're going to use the variables again, do this instead: | Code: | | label3.Text = (int.Parse(label1.Text) + int.Parse(label2.Text)).ToString(); |
