如何通过for循环将多个文本框值放入数组

Question

I got several textbox object on designer interface, let's say txtF1_ZHTW, txtF2_ZHTW, txtF3_ZHTW.

How to put the value of this 3 textbox into an array by a for loop?

The syntax I used for now is the worst way:

fieldName_TW[0] = txtF1_ZHTW.Text;
fieldName_TW[1] = txtF2_ZHTW.Text;

For what I want to proceed is something like...

for(i=0;i<3;i++)
{
    fieldName_TW[i] = txtF[i+1]_ZHTW.Text;
}

So, how can I modify the code to use a for loop to enter the value of multiple textbox to an array?

Answer 1

Put your textboxes in a collection, such as a List<TextBox> , so you can iterate it.

var texboxes = new List<TextBox>()
{
  txtF1_ZHTW,
  txtF2_ZHTW
};

// ...

foreach(var textbox in textboxes)  // Assumes that  fieldName_TW is large enough
   fieldName_TW[i] = textbox.Text

Answer 2

I wouldn't rely on a name to make that kind of loop. Make a collection of your textboxes and add them in the right order, so you can use correct indexes to read them:

List<TextBox> textBoxes = new List<TextBox>() { txtF1_ZHTW, txtF2_ZHTW, txtF3_ZHTW };

Use the for-loop you already showed:

for(int i=0; i < textBoxes.Count; i++)
{
   fieldName_TW[i] = textBoxes[i].Text;
}
