一、图片
1、在前端用<asp:FileUpload ID="UpImgName" runat="server"/>控件
2、在后台.cs中写上
protected void btnSubmit_Click(object sender,EventArgs e)
{
string strImgPath=string.Empty;
string strDateTime=dateTime.Now.Tostring("yyyyMMddhhmmss");
strImgPath=this.UpImgPath.PostedFile.FileName;
if(strImgPath!="")
{
string extension="";//扩展名
extension=Path.GetExtension(strImgPath).ToLower();
if(extension==".jpg"||extension==".jpeg"||extension==".bmp||extension==""gif")
{
if(this.UpImgPath.PostedFile.ContentLength>1000000)//图片大小是否大于1M
{
Response.Write("<script>alert(‘图片太大‘)</script>");
return;
}
strImgPath="/Images/"+strDateTime+extension;
string UpPath=Server.MapPath(strImgPath);
this.UpImgPath.PostedFile.SaveAs(UpPath);
}
else
{
Response.Write("<script>alert(‘图片格式错误‘)</script>");
return ;
}
}
}
二、视频,文件
1、在前端用<asp:FileUpload ID="UpVideoName" runat="server"/>控件
2、在后台.cs中写上
protected void btnSubmit_Click(object sender,EventArgs e)
{
string strVideoPath=string.Empty;
string strDateTime=DateTime.Now.Tostring("yyyyMMddhhmmss");
strVideoPath=this.UpVideoName.PostedFile.FileName;
if(strVideoPath!="")
{
string extension="";
extension=Path.GetExtension(strVideoPath).ToLower();
if(extension==".flv" || extension == ".doc" || extension == ".docx" || extension == ".zip" || extension == ".rar")
{
if(this.UpVideoName.PostedFile.ContentLength>30000000)
{
Response.Write("<script>alert(‘视频或文件太大‘)</script>");
return;
}
strVideoPath="/VideoOrFile/"+strDateTime+extension;
string UpPath=Server.MapPath(strVideoPath);
this.UpVideoName.PostedFile.SaveAs(UpPath);
}
else
{
Response.Write("<script>alert(‘存储的格式不正确‘)</script>")
return;
}
}
}
