，但現在我想知道我可以從數據庫中獲取的圖片到PictureBox

你能幫我嗎。

    ofdFoto.ShowDialog(); 
    string i = ofdFoto.FileName.ToString(); 
    pbxFoto.ImageLocation = i; 
} 

private void button2_Click(object sender, EventArgs e) 
{

    string querys = "INSERT INTO Fruits (Name, Picture) VALUES ('" + txtName.Text + "','" + ImageToByte(pbxFoto.Image) + "')"; 
    OleDbCommand cd = new OleDbCommand(querys, dbConn); 
    cd.ExecuteNonQuery();

試試這個代碼：

public static Bitmap BytesToBitmap(byte[] byteArray) 
{ 
    using (var ms = new MemoryStream(byteArray)) 
    { 
     var img = (Bitmap)Image.FromStream(ms); 
     return img; 
    } 
} 

，並設置爲PictureBox.Image屬性：

pictureBox1.Image = BytesToBitmap(byteArray);
