Question

我没有获得许可 How to store image in SQL Server database tables column（直接从对话框中插入图像），所以我创建了一个用于打开图像的小程序，并将其十六进制代码手动插入到表中，但它不起作用。

我认为它可以是转换，我曾尝试过

    byte[] arrBytes;

    //convert image to bytearray
    public byte[] imgToByteArray(Image img)
    {
        using (MemoryStream mStream = new MemoryStream())
        {
            img.Save(mStream, img.RawFormat);
            return mStream.ToArray();
        }
    }

    private void button1_Click(object sender, EventArgs e)
    {
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            Image imagen = Image.FromFile(openFileDialog1.FileName);
            pictureBox1.Image = imagen;
            arrBytes = imgToByteArray(imagen);         
        }
    }

    private void button2_Click(object sender, EventArgs e)
    {
        string hex = BitConverter.ToString(arrBytes).Replace("-", string.Empty);
        //string hex = BitConverter.ToString(arrBytes);
        //string hex = Convert.ToBase64String(arrBytes);

        richTextBox1.Text = hex;
    }

我得到了这段代码：

但是当我在sql server管理中进行插入时，代码会改变！

我的想法是使用像

这样的字节数组读取数据

Dim mStream As System.IO.MemoryStream = New System.IO.MemoryStream(abyIcono)
nuevaPbx.Image = Image.FromStream(mStream)

但不起作用，因为阵列不一样！（我接受了错误的参数错误）

将图像手动存储在SQL Server中的列图像
