ArgumentOutOfRangeException發生

Question

我會做一個程序，你可以選擇你的照片從電腦到圖像列表和列表視圖，然後如果你點擊任何照片，你可以在圖片框中查看它。開始時，我打開列表視圖中的多張照片的問題首先點擊第一張照片是沒有問題的，但是當你想裏面顯示的二次圖象到圖片框，然後我得到這個錯誤：

ArgumentOutOfRangeException發生

異常拋出： 'System.ArgumentOutOfRangeException' 在 System.Windows.Forms.dll中

其他信息： '0'= InvalidArgument值是無效的 '索引'。

你能幫幫我嗎？

public partial class TimeLapseForm : Form 
    { 
     public TimeLapseForm() 
     { 
      InitializeComponent(); 
     } 

     int resimSayac = 0; 
     List<string> resimKonumu = new List<string>();

     {

     private void listView1_SelectedIndexChanged_1(object sender, EventArgs e) 
     { 
      pictureBox1.Image = Image.FromFile(resimKonumu[listView1.SelectedIndices[0]]); 
     } 
    } 
}

您應該保護listView1_SelectedIndexChanged_1處理程序與未選定的索引。

private void listView1_SelectedIndexChanged_1(object sender, EventArgs e) 
{ 
    if (listView1.SelectedIndices.Count == 0) 
    { 
     return; 
    } 

    pictureBox1.Image = Image.FromFile(resimKonumu[listView1.SelectedIndices[0]]); 
}
