保存超出範圍C＃

Question

我想創建一個程序，用戶可以在datagridview中對單元格進行着色，然後將datagridview保存爲圖像。但是，當我按照需要生成我的datagridview時，我遇到了範圍問題。

我想不出一種很好的（而且很快）的方式來重構這種方式是有道理的。如何避免我的datagridview超出範圍在這種情況下？

謝謝！

public partial class Form2 : Form 
{ 
    bool erasing = false; 
    public Form2() 
    { 
     InitializeComponent(); 
    } 

    private void Form2_Load(object sender, EventArgs e) 
    { 
     dataGridView1.ColumnCount = Properties.Settings.Default.Width; 
     dataGridView1.RowCount = Properties.Settings.Default.Height; 
     dataGridView1.RowHeadersVisible = false; 
     dataGridView1.ColumnHeadersVisible = false; 
     dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.AllCells; 
     dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells; 
     dataGridView1.AutoSize = true; 
     dataGridView1.ClearSelection(); 
     dataGridView1.DefaultCellStyle.SelectionBackColor = Color.Black; 
     dataGridView1.CellClick += new DataGridViewCellEventHandler(dataGridView1_CellClick); 
    } 

    void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) 
    { 
     if (erasing) 
     { 
      dataGridView1.DefaultCellStyle.SelectionBackColor = Color.White; 
      dataGridView1[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.White; 
     } 
     else 
     { 
      dataGridView1.DefaultCellStyle.SelectionBackColor = Color.Black; 
      dataGridView1[e.ColumnIndex, e.RowIndex].Style.BackColor = Color.Black; 
     } 
    } 

    private void checkBox1_CheckedChanged(object sender, EventArgs e) 
    { 
     if (checkBox1.Checked) 
     { 
      erasing = true; 
     } 
     else 
     { 
      erasing = false; 
     } 
    } 

    private void savegviewImg() 
    { 
     Bitmap bmap = new Bitmap(DataGridView1.Bounds.Width, DataGridView1.Bounds.Height); 
     DataGridView1.DrawToBitmap(bmap, new Rectangle(1, 1, DataGridView1.Width, DataGridView1.Height)); 
     bmap.Save("C:\\HelpMehStackOFlowYoureMyOnlyHope.jpeg", System.Drawing.Imaging.ImageFormat.Jpeg); 
    } 

} 

}

應當dataGridView1和不DataGridView1在savegviewImg（）方法，沒有？這就是你在其他地方引用它的方式。
