现在来玩玩图片上传
这里用到一个HTMl控件，FileField作为服务器控件运行
private void btnUpLoad_Click(object sender, System.EventArgs e)
{
string fullFileName=this.File1.PostedFile.FileName;
string fileName=fullFileName.Substring(fullFileName.LastIndexOf("//")+1);
string type=fullFileName.Substring(fullFileName.LastIndexOf(".")+1);
if(type=="jpg"||type=="bmp"||type=="gif")
{
this.File1.PostedFile.SaveAs(Server.MapPath("up")+"//"+fileName);
this.Image1.ImageUrl="up/"+fileName;
}
else{
Response.Write("<script language='javascript'>alert('你输入的格式不对');</script>");
}
}
