我可以知道我可以在Razor中写这样的c#Opendialog吗？我正在尝试制作一个openfiledialog,它可以让用户将照片上传到SqlServerCe数据库:

OpenFileDialog openFileDialog1 = new OpenFileDialog();

openFileDialog1.InitialDirectory = "c:\\";
openFileDialog1.Filter = "All files (*.*)|*.*";
openFileDialog1.FilterIndex = 2;
openFileDialog1.RestoreDirectory = true;

if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
   try
   {
      string path = openFileDialog1.FileName;
      byte[] image = File.ReadAllBytes(path);
      string query = "UPDATE firma SET logo=@Image WHERE id = 1";
      SqlCommand sqlCommand = new SqlCommand(query, conn);
      sqlCommand.Parameters.AddWithValue("@Image", image);
      conn.Open();
      sqlCommand.ExecuteNonQuery();
      conn.Close();
   }
   catch (Exception ex)
   {
      MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
   }
