how to write multiple functions in StreamWriter

Hello Friends,

Actually I want to know how to use multiple functions in StreamWriter, Streamwriter is used to write some selected content from the checklist box to notepad.

For ref. code

//Function 1

public void getSelectedColumnName()

{

string selectedColumn = "";

for (int i = 0; i < chkListBxColumnName.Items.Count; i++)

{

selectedColumn += chkListBxColumnName.Items[i] + ",";

}

StreamWriter SwriteData = new StreamWriter(@"C:\Users\user\Desktop\ReportTmplate\TemplateName.txt");

}

//Function 2

public void getSelectedTableName()

{

string selectedColumn = "";

for (int i = 0; i < chkListBxTableName.Items.Count; i++)

{

selectedColumn += chkListBxTableName.Items[i] + ",";

}

StreamWriter SwriteData = new StreamWriter(@"C:\Users\user\Desktop\ReportTmplate\TemplateName.txt");

}

//Now I want to call these above 2 functions in stream writer

private void btnWriteData_Click(object sender, EventArgs e)

{

using (StreamWriter write = new StreamWriter(@"C:\Users\user\Desktop\ReportTmplate\Template.txt"))

{

write.WriteLine(lblDBFileName.Text + " [" + cmbDBFileName.Text + "]\n");

write.WriteLine(lblDbTableName.Text + " [" + cmbDbTableName.Text + "]\n");

// Now Inside this function block, I want to use Function 1 & Function 2, below the above line.

//So please how can use this function here.

}
