I have searched and searched but cant see to find an answer to my problem. I want to get the selected text from a combobox on form1 and use it to search in a file from a class file. an example of what im looking to do is

C#

if (line.Contains(Form1.Combobox1.SelectedItem))
  {
    /*search code here*/
  }

where Combobox1.SelectedItem is what was chose on form1. I'm new to C# and could accomplish this in Vb but am wanting to learn a new language.

Do you know how to do it in VB or in VB.NET? If VB.NET, with C# this is exactly the same.

The question is not clear; and it is not clear why do you use Contains. It looks like you just need a text of a selected item:

C#

object selectedItem = Form1.Combobox1.SelectedItem;
if (selectedItem != null) { //important check
    string selectedText = selectedItem.ToString();
    //...
}

Please do yourself a favor: never leave ugly auto-generated names like Form1, Combobox1, renamed all of them to give them some semantic names. Those auto-generated names even violate Microsoft naming conventions — test your assembly by FxCop to see. Why do you thing you have a refactoring engine?

A bit more searching and i was able to find a way to work out the code. as i said i'm still learning so what i muddle though at this point is dirty at best, but i am getting the gist of it. i wont post my fix cause as i said it's real dirty.

@SAKryukov
thanks for the direction. the auto-generated MS names were just an example of what i was wanting to do(thought the type of control would be relevant to the answer). the "class file" i was referring to was when you add a "Class" to the project so all my code would not be in the "Form" file. As for FxCop i seem to have a problem installing it but thats another topic. As for the vb or vb.net, i thought vb.net but after looking into the differences between the 2 im gonna have to say just plain-old vb.

Use this

C#

string a=Form1.Combobox1.Text; //Here you will get the selected text that you have choose in comboBox 
//Hope this will help you

then you can assign the 'a' variable to your search class
