这是情况:
Update()
方法都会引发以下异常:$ exception {“ GDI +中发生一般错误。”} System.Runtime.InteropServices.ExternalException
此方法引发此错误:
private byte[] ImageToByteArray(Image imageIn)
{
using (var ms = new MemoryStream())
{
imageIn.Save(ms, imageIn.RawFormat);
return ms.ToArray();
}
}
这是我的GetParams()
方法,其中正在使用ImageToByteArray
:
private void GetParams()
{
Ebm.ResetParams();
Ebm.Params.Id = IdTextBox.Text.GetInt();
Ebm.Params.EmployeeCode = Ebm.GenerateEmployeeCode();
Ebm.Params.LastName = LastNameTextBox.Text;
Ebm.Params.FirstName = FirstNameTextBox.Text;
Ebm.Params.MiddleName = MiddleNameTextBox.Text;
Ebm.Params.GenderId = GenderBox.SelectedValue.GetInt();
Ebm.Params.BirthDate = BirthDatePicker.Value.GetDateTime();
Ebm.Params.Age = AgeTextBox.Text.GetInt();
Ebm.Params.Salary = SalaryTextBox.Text.GetDecimal();
Ebm.Params.StatId = 1;
if (PixPictureBox.Image != null)
{
Ebm.Params.Pics = ImageToByteArray(PixPictureBox.Image);
}
}
这是我用来将图片从数据库加载到PixPictureBox的方法
private Image ByteArrayToImage(byte[] bytesArr)
{
using (var memstr = new MemoryStream(bytesArr))
{
Image img = Image.FromStream(memstr);
return img;
}
}
这是我的加载方式:
private void LoadDetails()
{
IdTextBox.Text = Ebm.Item.Id.GetString();
EmployeeCodeTextBox.Text = Ebm.Item.EmployeeCode;
LastNameTextBox.Text = Ebm.Item.LastName;
FirstNameTextBox.Text = Ebm.Item.FirstName;
MiddleNameTextBox.Text = Ebm.Item.MiddleName;
GenderBox.SelectedValue = Ebm.Item.GenderId;
BirthDatePicker.Value = Ebm.Item.BirthDate;
AgeTextBox.Text = Ebm.Item.Age.GetString();
SalaryTextBox.Text = Ebm.Item.Salary.GetString();
try
{
PixPictureBox.Image = ByteArrayToImage(Ebm.Item.Pics);
}
catch (Exception ex)
{
PixPictureBox.Image = null;
}
}
我还从我的MemoryStream中得到了一个我认为与异常有关的错误:
答案 0 :(得分:0)
我只需要将[13:26:34] -> POST 202 [message] hello
[13:26:35] <- POST 200 Reply[message] Hello
[13:26:35] <- POST 200 Reply[event] Debug Event
[13:26:38] -> POST 202 [message] hi
[13:26:39] <- POST 200 Reply[message] Hola
[13:26:39] <- POST 200 Reply[event] Debug Event
[13:26:46] -> POST 202 [message] status of Ankita
[13:26:48] <- POST 200 Reply[message] Status of Ankita is RolledOn!
[13:26:48] <- POST 200 Reply[event] Debug Event
[13:56:20] -> POST 202 [conversationUpdate]
[13:56:20] -> POST 202 [conversationUpdate]
[13:56:31] -> POST 202 [message] Hi
[13:56:32] <- POST 200 Reply[event] Debug Event
[13:56:33] <- POST 200 Reply[message] Hola
[13:56:33] <- POST 200 Reply[event] Debug Event
方法更改为此:
ByteArrayToImage()
