Sending a string varible from one form to another via button click event

Question

Hi there I am new to C# and was wondering if someone can help me with an issue with a windows app that I am currently working on? I have two forms Form1 and Form2 I have a string varible in both forms. I call Form2 from Form1 via a menu option and would like to send a string value from Form2 to Form1 via a button click event. The idea is that the user will go itno the options menu on Form1 go to Form2 and make changes to the layout etc which calls a file location string to be passed back to Form1 when the user clicks OK. I have manged to call Form2 from Form1 ok using the below but I am not sure how to pass the string back once the user has finished? I would be greatful if someone could point me in the right direction?

Code for the value of one text box on form1 to another textbox on form 2 example: : There are 2 forms form1 and form 2 onclick event of button1 on form1 write this code private void button1_click() { form2 xx=new form2(); //this will contain value of textbox1 on form1 //Tag value is int by default we have to convert into string xx.Tag=textBox1.Text; xx.Show(); } //now form2 coding private void form2_load() { //showing value of Textbox1 on form2 text box textBox2.Text=Convert.ToString(this.Tag); }
