大家帮忙看看这怎么回事?

var dtsource = from s in link.VendorRegLog
select new
{
s.FID,
s.FVendorID,
s.FBatch,
s.FMobImei,
s.FAutoCpuID,
s.FAutoBtID,
s.FAutoWifiID,
s.FAutoOs,
s.FAutoIP,
s.FDatetime,
s.FResult,
s.FFailCaurse,
s.FRegTimes
};

if (SDate.Text != "" && EDate.Text != "")
{
dtsource = dtsource.Where(s => ((DateTime.Parse(s.FDatetime) >DateTime.Parse(SDate.Text))&& (DateTime.Parse(s.FDatetime) <= DateTime.Parse(EDate.Text))));
}

GridView1.DataSource = dtsource;
GridView1.DataKeyNames = new[] { "FID" }
GridView1.DataBind();
错误：方法“System.DateTime Parse(System.String)”不支持转换为 SQL。

just use Convert.ToDateTime() instead of DateTime.Parse()
