试图写入结果并将结果附加到文件

Question

下面我的（相当）简单的应用程序的下面的图像是它的代码。我需要知道如何将comboBox1（Location），comboBox2（Medication），textBox1（Quantity）和textBox2（Date）导出到CSV或Excel类型的文件中，以运行报告。我是C＃的两周新手，并且可以真正使用帮助，因为我一直在做这方面的工作，具体工作了大约一周！

namespace WindowsFormsApplication1 
{ 
     public partial class Form1 : Form 
     { 
       public Form1() 
       { 
        InitializeComponent(); 
       } 

       private void button1_Click(object sender, EventArgs e) 
       { 

       } 

       private void button2_Click(object sender, EventArgs e) 
       { 

       } 

       private void button3_Click(object sender, EventArgs e) 
       { 
        Application.Exit(); 
       } 

       private void exitToolStripMenuItem_Click(object sender, EventArgs e) 
       { 
        Application.Exit(); 
       } 

       private void toolStripMenuItem1_Click(object sender, EventArgs e) 
       { 
       } 

       private void comboBox1_SelectedIndexChanged(object sender, EventArgs e) 
       { 
       } 

       private void dateTimePicker1_ValueChanged(object sender, EventArgs e) 
       { 
        dateTimePicker1.CustomFormat = "dd/MM/yyyy"; 
        dateTimePicker1.MinDate = DateTime.Today; 
        dateTimePicker1.MaxDate = DateTime.Today; 
       } 

       private void label4_Click(object sender, EventArgs e) 
       { 
       } 

       private void textBox2_TextChanged(object sender, EventArgs e) 
       { 
        textBox2.Text = DateTime.Now.ToString(); 
       } 


     }
