How to encode names in C #

Question

I have 10 text fields, namely TB1, TB2, TB3, TB4, etc. on TB10

I want to save them in a single string value with a name in BeStored.

Now i do the manual way

String toBeStored=null;
tobeStored=TB1.text.toString();
tobeStored+=TB2.text.toString();

etc.

I want to create a for loop and add them

something like that..

for(int i=1;i<11;i++)
{
      toBeStored+=TB+i+.text.ToString()+"  ";
}

I know this is wrong .. everything to do it right?

Answer 1

No. Since you defined text fields as variables, there is simply no enumerator.

You can define your own counter. In the simplest case, which is as simple as

TextBox boxes [] = new TextBox [] { TB1, TB2, TB3....}

foreach (TextBox box in boxes) {
}

Answer 2

Although I think the premise may be wrong, you can do it with

for (int i = 1; i <= 10 ; i++) {
  TextBox textbox = (TextBox)Page.FindControls( "TB" + i.ToString);
  toBeStored += textbox.Text;
}

Secondly, you probably do not need to use .ToString () in the Text property, which I would assume is already a string.

Finally, if you insist on laziness, add the text fields to the array and go through the array:

private TextBox[] _textBoxes = new TextBox[10];

// In init code:
TextBox[0] = TB1;
TextBox[1] = TB2;
// ...

StringBuilder toBeStored = new StringBuilder();
for (int i=0; i<10; i++)
{
   toBeStored.Append(TextBox[i].Text);
}

// Now process toBeStored.ToString();

Answer 5

You can use reflection at all if you want to get the field by name.

Type type = GetType();
for (int i = 1; i <= 10; i++)
{
    var name = "TB" + i;
    var field = type.GetField(name, BindingFlags.Instance | BindingFlags.NonPublic); //or appropriate flags
    TextBox tb = (TextBox)field.GetValue(this);
    //...
}

Answer 6

If this were done, I would create a helper method for accumulating text into a string.

    public string AccumulateNames(params string[] names)
    {
        return names.Aggregate(string.Empty, (current, name) => current + name);
    }

which will be called similar

var toBeStored = AccumulateNames (TB1.Text, TB2.Text, ..., TBn.Text);
