关于ASP.net上传图片
同一段代码，上传.txt文件是完好的，上传图片和.exe文件就只有一个空壳，没有内容的
这是我的代码：
string filepath = FileUpload1.PostedFile.FileName.ToString();
string filename = filepath.Substring(filepath.LastIndexOf("\") + 1);
string serverpath = HttpContext.Current.Server.MapPath("file/") + filename;
int pos = filename.LastIndexOf(".");
string lastname = filename.Substring(pos, filename.Length - pos);
FileUpload1.PostedFile.SaveAs(serverpath);
求指导，。。，
[解决办法]
protected void pictureUpLoad_Click(object sender, EventArgs e)
{
//获取图片名称
string fileName = picUpload.FileName;
if (fileName != "")
{
//将图片名称都同意格式化yyyyMMddHHmmss+后缀
String randomStr = "Img" + DateTime.Now.ToString("yyyyMMddHHmmss", DateTimeFormatInfo.InvariantInfo);
string lastName = randomStr + System.IO.Path.GetExtension(this.picUpload.FileName); //名字+后缀
//设置图片路径
string path = Server.MapPath("~/images/Joins/");
//保存图片
picUpload.SaveAs(path + lastName);
txtImage.Text = lastName;
}
else
{
ui.Alert(this, "不能上传空文件");
}
}
////获取全中的文件路径
//string filepath = this.FileUpload1.FileName;
////获取文件名
//string name = filepath.Substring(filepath.LastIndexOf('/')+1, filepath.Length);
////获取服务器路径
//string path = Request.MapPath("file");
////保存
//this.FileUpload1.SaveAs(path+"/"+name);
string filepath = FileUpload1.PostedFile.FileName.ToString();
string filename = filepath.Substring(filepath.LastIndexOf("\") + 1);
string serverpath = HttpContext.Current.Server.MapPath("file/") + filename;
int pos = filename.LastIndexOf(".");
string lastname = filename.Substring(pos, filename.Length - pos);
FileUpload1.PostedFile.SaveAs(serverpath);
}
