Re: string to a command

Ok, I think I´ve explained it wrong. (Please correct me if I make mistakes with my englisch).

I have a string called 'str'. In this string is one part of a Command. str = "textBox12".
Now, I must read the textBox12. Str says to me, which textBox I must read. In this textBox12 is an integer=12 (for example)

So I want a command like:

int a = ConvertToInt16(str.Text)

str.Text stands for textBox12.Text

I hope I´ve explained it better.

Ah.

Iterate through the form's Controls collection to get at the named control.
Use Int16.TryParse() to convert the .Text property of that control to an integer.

ok, it doesn´t work. I´ve got the error, that I need an object reference for form1.controls.
Can you explain it with other words please?

That code won't work if the target control is in the Controls collection of a container, such as a GroupBox or Panel. You should make a recursive method which iterates ControlCollections searching for a control with the specified name.

An easier way to do this would be to use reflection to get the control by it's name, assuming that the control is not created dynamically. For example:

FieldInfo fi = this.GetType().GetField( "textBoxInfinity", BindingFlags.Instance | BindingFlags.NonPublic );
TextBox txt = fi.GetValue( this ) as TextBox;
txt.Text = "HELLO";

You´re right. I noticed it, because my textBoxes were in GroupBoxes Big Grin | :-D

No, it would be better to say "I had not heard of reflection."

Totally agree Josh, but as the OP seemed confused already I thought starting simple was the best way to go.

Had the poster come back and said "It does not work because textbox12 is inside a panel", then I would have delved into the obvious recursive method!

My concern was that the OP's confusion might indicate that he/she wouldn't necessarily make the connection between the fact that the TextBox was in a GroupBox and the fact that the provided method did not work as provided. Rose | [Rose]

Oh...it was my first thouhgt. I reallized that all Boxes around were detected only. So I tested it without a groupBox and voila it works.

1. int.Parse(textBox12.Text);
2. Convert.ToInt32(textBox12.Text);

I want to use Global Variable concept in C#.NET Project

Please help me how to do it ?

Store that data in a class and pass an instance (i.e. the same instance) of that class to each form. You may want to consider using a singleton pattern[^].
