Promblemas發送調用我的方法到一個按鈕

Question

我在C＃學習編程，所以我的問題是，如何調用從BUTTON3 查找網絡上的信息的方法，但它也不是很清楚，我爲什麼打開這個網站

private void button3_Click_1(object sender, EventArgs e) 
{  
} 

private void export2File(ListView lv, string splitter) 
{ 
    string filename = ""; 
    SaveFileDialog sfd = new SaveFileDialog(); 

    sfd.Title = "SaveFileDialog Export2File"; 
    sfd.Filter = "Text File (.txt) | *.txt"; 

    if (sfd.ShowDialog() == DialogResult.OK) 
    { 
     filename = sfd.FileName.ToString(); 
     if (filename != "") 
     { 
      using (StreamWriter sw = new StreamWriter(filename)) 
       { 
        foreach (ListViewItem item in lv.Items) 
        { 
         sw.WriteLine("{0}{1}{2}", item.SubItems[0].Text, splitter, item.SubItems[1].Text); 
        } 
       } 
      } 
     } 
    } 

Answer 1

private void button3_Click_1(object sender, EventArgs e) 
{  
    ListView listView1 = new ListView(); 
    string splitter = ","; 

    export2File(listview1, splitter); 
} 

Answer 2

你需要通過你的表格到ListView控件的引用，所需的「分流」到方法。假設listView1和一個逗號：

private void button3_Click_1(object sender, EventArgs e) 
{  
    export2File(listView1, ","); 
}
