Your question is not clear. If you assign the text of a textbox with jobtitle it will be overwritten with each st2 in the list

You just need to decide which of the elements in the list you want to save, and stop the loop at that point. As it stands jobtitle will always contain the value of the last item.

It's not clear what you are trying to do with this code. "User this variable in another place" is not that goal. What are you trying to do with the data in st2? (bad variable name by the way)

I doubt you need to use the Convert class; please don't. Try using a cast instead. You also don't need the local variable prop.
Do you want to maybe fill a List<string> with the values?

Your question is very unclear...

Using your code and keeping in mind that the 'jobtitle' will change with every iteration of your loop, you can try the following, which will only show the last record in the loop -

C#

//Using a TextBox named textBoxJobTitle in your form...
string jobtitle = ""; 
//Make sure to initialize your variable

if (st2 != null)
{
    foreach (var item in st2)
    {
        var prop = item.UserJobTitle;
        jobtitle = Convert.ToString(prop);
    }
}

//Now use the jobtitle value into your TextBox text
textBoxJobTitle.Text = jobtitle;

Your code iterating through the items in st2 (collection of objects) and extract the UserJobTitle property from each item. If you only need the last UserJobTitle in the loop and want to use it in another place (like a TextBox), then refer to the Solution-2.
If you want to set the value in another place (like a TextBox) upon a condition then you can modify your code as:

C#

if (st2 != null)
{
	foreach (var item in st2)
	{
		// Your condition to check the job title, here you can use a string constant or enum
		if(Convert.ToString(item.UserJobTitle) == "AnyJobTitle")
		{
			textBoxJobTitle.Text = Convert.ToString(item.UserJobTitle);
		}
	}
}
