我有一个表格,我想将上传的图像存储到数据库中并将这些图像发送到邮件中。
首先,我将图像存储在数据库中,然后将图像附加到正在发送的邮件中,但是我的问题是我没有在邮件中获取上载的图像。显示错误
我们不支持此文件格式
将图像转换为二进制格式的代码:
Byte[] bytImage = new byte[] { 1 };
Byte[] bytImage1 = new byte[] { 1 };
Byte[] bytImage2 = new byte[] { 1 };
Byte[] bytImage3 = new byte[] { 1 };
Byte[] bytImage4 = new byte[] { 1 };
for (var x = 0; x < Request.Files.AllKeys.Length; x++)
{
HttpPostedFile file = Request.Files[Request.Files.AllKeys[x]];
if (file != null && file.ContentLength > 0)
{
try
{
HttpPostedFile objHttpPostedFile = file;
int intContentlength = objHttpPostedFile.ContentLength;
if (x == 0)
{
bytImage = new Byte[intContentlength];
objHttpPostedFile.InputStream.Read(bytImage, 0, intContentlength);
}
else if (x == 1)
{
bytImage1 = new Byte[intContentlength];
objHttpPostedFile.InputStream.Read(bytImage1, 0, intContentlength);
}
else if (x == 2)
{
bytImage2 = new Byte[intContentlength];
objHttpPostedFile.InputStream.Read(bytImage2, 0, intContentlength);
}
else if (x == 3)
{
bytImage3 = new Byte[intContentlength];
objHttpPostedFile.InputStream.Read(bytImage3, 0, intContentlength);
}
else if (x == 4)
{
bytImage4 = new Byte[intContentlength];
objHttpPostedFile.InputStream.Read(bytImage4, 0, intContentlength);
}
}
catch (Exception ex)
{
throw ex;
}
}
}
将图像发送到邮件的代码:
message.IsBodyHtml = true;
for (int x = 0; x < Request.Files.Count; x++)
{
HttpPostedFile PostedFile = Request.Files[x];
if (PostedFile != null && PostedFile.ContentLength > 0)
{
try
{
message.Attachments.Add(new
Attachment(PostedFile.InputStream,PostedFile.FileName));
}
catch (Exception ex)
{
throw ex;
}
}
}
