@H_502_1@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);
}
