调用：

}

{
string fileName = file.FileName; // 获得上传上文件的名称,完整名称,如: aa.txt

// 限制文件格式

前端调用：

// 下载亲情号码模板
function DownLoadFimlyPhoneTempletFile() {
var f = $('<form action="/SchoolPhone/FamilyPhone/DownLoadFimlyPhoneTempletFile" method="post" id="ExportFimlyPhoneTempletFile"></form>');
f.appendTo(document.body).submit();
try {
document.body.removeChild(f);
} catch (e) { }
}
</script>
