So I have button_click event which generate files. I want to close it after I click this button event. If I use close() at end of button click conditions, some of my functions isnt doing all their job. Maybe there is other way to close button event?

C#

private void button2_Click(object sender, EventArgs e)
           {
               {
                   var header = File.ReadAllText(@"C:\dir\header.tex");
                   var footer = File.ReadAllText(@"C:\dir\footer.tex");
                   var sb = new StringBuilder();

                   sb.AppendLine(header);

                   foreach (TreeNode node in treeView1.Nodes)
                   {

                       var tag = node.Tag as string;
                       sb.AppendLine(string.IsNullOrEmpty(Text) ? node.Text : tag);

                   }
                        sb.AppendLine(footer);
   File.WriteAllText(@"C: \dir\final.tex", sb.ToString());

                     //Close() I were using close here.
               }

Close button or close a form? What are you wanting to close?

Member 12175492 2-Dec-15 9:29am

close form. It is closing, but Last part appenline loses tag value. Other parts are working well. without close() all parts working well

var tag = node.Tag as string;
sb.AppendLine(string.IsNullOrEmpty(Text) ? node.Text : tag);

that doesn't look right: do you mean:

var tag = node.Tag as string;
sb.AppendLine(string.IsNullOrEmpty(tag) ? node.Text : tag);

It is how I wrote it. I don't why you don't like my code :) main problem for how to close form after this button click.

It's how you wrote it but it does not do what you want... So you better listen to advises that are given to you, especially when they come from someone that has proven to be a valuable asset to this site for many years. The question is not "liking your code or not", the question is "Is this code sematically correct ?". And, given the informations you provided, it is not. Especially, could you answer these few questions:
- What is the Text variable you are using?
- Where is it defined?
- Did you add it to your Form class, or do you mean to access the Text property of a given control?

I think, it is better to do as much as possible everything in your way. This line which you say that I am doing wrong, is checking if my tree view node with some sort of text(file name) is added and if its added so its tag(string info which needed to be add to generate latex file) is being added to my main latex file. I forget to put #TreeView so then this would be that text is node name and tag is some added value to the node. In my opinion, this problem has easy solution , I am not putting close in right place or there is some method how to close that form which I don't know yet, I am kinda new to c#, programming only few weeks with this language.

I found my mistake, As I thought I was just putting Close() not in right place. Thanks for your time.

Your code is not making any sense. This line:

sb.AppendLine(string.IsNullOrEmpty(Text) ? node.Text : tag);

says if Text (whatever that is, it's not defined in the code snippet you posted) is null or String.Empty, append the node.Text content to the string builder. If Text is not null or empty, append the node.Tag contents.

What's Text, because that's what is driving what gets appended and is probably not what you expect.

Learn to the use the debugger and step through code and inspect variable contents. Without that skill, you're just guessing at what's wrong with your code.
