Question

ASP.net如何将图片保存到指定的路径

Answer 1

protected void Button1_Click(object sender, EventArgs e)
{
string constr = ConfigurationManager.ConnectionStrings["conn"].ConnectionString.ToString();

string fullname = FileUpload1.PostedFile.FileName;
FileInfo fi = new FileInfo(fullname);
string name = fi.Name;
string type = fi.Extension;
if (".gif" == type || ".jpg" == type || ".Gif" == type || ".JPG" == type)
{
/族简/者码定义保存图片的路径
string savepath = Server.MapPath("~/image");
//保存上传的图片
FileUpload1.PostedFile.SaveAs(savepath + "\\" + name);
string picurl=savepath+"\\"+name;
Response.Write("<script>alert('图片上传成功')</script>");
try
{
SqlConnection conn = new SqlConnection(constr);
string instr = "insert into picture (picurl) values ('"+picurl+"') ";
conn.Open();
SqlCommand cmd = new SqlCommand(instr,conn);
cmd.ExecuteNonQuery();

Image1.ImageUrl = "image" + "/" + name;
}
finally
{
new SqlConnection().Close();
}
}
else
{
Response.Write("<script>alert('请选择gif和jpg格式的图兆嫌裤片！')</script>");
}
}

Answer 2

private
void
copyfile(string
sources,
string
dest)
{
directoryinfo
dinfo=new
directoryinfo(sources);//注，这里面传的是路径，并不是文件，所以不能保含带后缀的文件
foreach(filesysteminfo
f
in
dinfo.getfilesysteminfos())
{
//目标路径destname
=
目标文件夹路径
+
原文饥缺件夹下的子文件(或文件夹)名字
//path.combine(string
a
,string
b)
为合并两个字符串
string
destname
=
path.combine(dest,
fsi.name);
if
(f
is
fileinfo)//如果是文件就复制
{
file.copy(f.fullname,
destname,
true);//true代表可以覆盖同并肢帆名文件
}
else//如果是文件夹就绝雹创建文件夹然后复制然后递归复制
{
directory.createdirectory(destname);
copyfile(f.fullname,
destname);
}
}
}
