我有一个像这样的保存按钮，其中我引用了上面的类，但我想向这个按钮添加图像，请查看下面的代码，看看你是否可以帮助我解决这个问题：
private void BTNSAVE_Click(object sender, RoutedEventArgs e)
try
if (txtFirstName.Text == "" || txtMiddelName.Text == "" || txtLastName.Text == "" || txtGuardianPhone.Text == "" || txtNationality.Text == "" || txtstate.Text == "" || txtGender.Text == "" || txtDisability.Text == "")
MessageBox.Show("Required Field:FirstName,MiddleName,LastName, \n GuardianPhone,State/Province,Gender, \n Nationality,Disability \n Save Aborted; enter accurate values");
else
using (SqlConnection conn = new SqlConnection(MYCONNEC))
c5.FirstName = txtFirstName.Text;
c5.MiddleName = txtMiddelName.Text;
c5.LastName = txtLastName.Text;
c5.Contact = txtContact.Text;
c5.GuardianPhone = txtGuardianPhone.Text;
c5.DOB = txtDOB.Text;
c5.Address = txtAddress.Text;
c5.State = txtstate.Text;
c5.Gender = txtGender.Text;
c5.Nationality = txtNationality.Text;
c5.Disability = txtDisability.Text;
bool success = c5.Insert(c5);
if (success == true)
LBLDP.Content = "Saved Successfully!!";
Refresh();
Clear();
else
MessageBox.Show("Contact Not Saved, Try Again");
catch (Exception ex)
MessageBox.Show(ex.Message, "MGT Message", MessageBoxButton.OK, MessageBoxImage.Error);
我想在此应用程序的保存按钮中添加c5.photo，有人可以帮我吗？
【问题讨论】：
【参考方案1】：您不能直接将图像保存在类对象和数据库中。为此，您可以通过两种方式做到这一点：
您从请求中获取图像，将其保存到您的服务器，并将该特定文件的路径保存在数据库中。这是实现这一目标的最佳方式，因为它不会对您的数据库大小产生任何影响。
如果您只想将文件保存在数据库中，则可以将数据库列数据类型用作 BLOB，这样您就可以保存文件或冗长的对象。在你的课堂上，你制作照片道具。作为字符串并将图像或文件的 base64 保存（推荐）或将属性设置为 Stream 并将文件流保存在此特定对象中并同样推送到数据库。
