问题描述
看看下面给出的行
字符串目标;
FileUpload1.FileContent.Seek( 0 ,SeekOrigin.Begin);
FileUpload1.PostedFile.InputStream.Read(pic, 0 ,len);
其中FileUpload是asp.net中的一个标签,用于上传文件.字符串目标已分配了一个jpeg文件.现在我想使用字符串目标代替Fileupload,有人可以告诉我如何使用它,或任何其他替代方法吗?
thnx
解决方案
要从fileUpload保存文件,最简单的方法是:
if(FileUpload1.HasFile) FileUpload1.SaveAs(target);
您必须根据需要使用正确的文件名来初始化目标.
为回应您在解决方案1中的评论,我给您更精确的解释.
我建议你:
1°)保存文件,如解决方案1中所述
2°)将已保存的ppt文件解析为jpg文件,如本链接中所述

解决方案
For saving a file from a fileUpload, the easiest way is :
if(FileUpload1.HasFile) FileUpload1.SaveAs(target);
You have to initialize target with a correct filename according your needs.
In response of your comment in Solution 1, i give you somme more precise explanation.
I suggest you to :
1°) save the file like mentionned in Solution 1
2°) parse the saved ppt file in jpg file like described in this link
