<input type="file" name="xxxxxxx"/>必须有“name”属性,否则在后台代码中用Request.Files是取不到值的
后台读取文件代码:
HttpFileCollection httpFileCollection = HttpContext.Current.Request.Files;
if (httpFileCollection.Count > 0)
{
HttpPostedFile file = httpFileCollection[0];
StreamReader reader = new StreamReader(file.InputStream);
StringBuilder strLicense = new StringBuilder();
do
{
strLicense.AppendLine(reader.ReadLine());
} while (!reader.EndOfStream);
return strLicense.ToString();
}
