Pass File Directory between button click

How can I pass file directory between two button click method?

  1. I'm selecting csv file and put the CSV name to TextBox

    private void Button_Click(object sender, RoutedEventArgs e)
{
  OpenFileDialog ofd = new OpenFileDialog();
  ofd.Filter = "CSV|*.csv";
  ofd.ShowDialog();

  csvName.Text = ofd.SafeFileName;           
}

  2. Second button should start reading CSV file selected into first step

    private void Button_Click_1(object sender, RoutedEventArgs e)
{
    //string path = ;
    StreamReader srd = new StreamReader();
}

csvName.Text = ofd.SafeFileName; SafeFileName doesn't return the full path it just returns the filename, which is not enough for the button(Button_Click_1) the start reading . Instead use ofd.FileName; this give the complete path. Assuming csvName as TextBox.

declare global variable 

public string FullFileName{get;set;}

private void Button_Click(object sender, RoutedEventArgs e)
{
 OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "CSV|*.csv";
ofd.ShowDialog();
csvName.Text = ofd.SafeFileName;

FullFileName=ofd.FileName; }

private void Button_Click_1(object sender, RoutedEventArgs e)
{
using(var reader = new StreamReader(FullFileName))
{
// do your action here
}
}

you can read the text of csvName in the button2_click event.

string path = csvName.Text;

or you can use a variable to save the value of the textbox and use that too.
