推荐答案

protected void btnSubmit_Click(object sender, EventArgs e)
{
try {
FileInfo TheFile = new FileInfo(MapPath(".") + "\\" + txtFile.Text);
if (TheFile.Exists) {
File.Delete(MapPath(".") + "\\" + txtFile.Text);
}
else {
throw new FileNotFoundException();
}
}

catch (FileNotFoundException ex) {
lblStatus.Text += ex.Message;
}
catch (Exception ex) {
lblStatus.Text += ex.Message;
}

}

文件位于images文件夹中.

如果您的数据库路径是这样的话

图片\ demo.jpg

files are in images folder.

if Your DB path is like this means

Images\demo.jpg

string dbpath=getdbValue() // get it from DB

string delfile= System.Web.Hosting.HostingEnvironment.ApplicationPhysicalPath +dbpath

System.IO.File.Delete(delfile);
