运行窗体时的Powershell输出问题

Question

When I run my Forms code I have different objects that are added to the Form (buttons, labels, etc) I attache the objects to the form by using the command $Form1.Controls.Add([ObjectType]) .

My question is, when I run my code I get an instant sequence of numbers in my console and output dialogue box of:

0 1 2 3 4 5 6 7 8 9 0 1 2

When after I click Submit button the string "OK" is added to the numbers shown above

0 1 2 3 4 5 6 7 8 9 0 1 2 OK

Why is this happening and how can I remove these or atleast omit them from displaying. The OK displays once the Submit button is pressed. OK

Answer 1

Some actions like .Add() are producing output. To prevent this, pipe the output into the [void] by adding | Out-Null | Out-Null at the end of the line or [void] directly infront of the variable that is used, like:

$foo.SomethingThatGeneratesOutput() | Out-Null

or

[void]$foo = SomethingThatGeneratesOutput

Answer 2

As T-Me has stated, to prevent output being generated when executing methods as you are use [Void].

[Void]$Form1.Controls.Add([ObjectType])

If your code is still returning unwanted data, open the script in PowerShell ISE, and execute the script line by line (select the line and press F8). This will help you determine which line of code is generating output still.
