GUID!!!!

sparaDetail = commDetail.Parameters.Add("@PARENTID", SqlDbType.NVarChar, 50);
2 commDetail.Parameters["@PARENTID"].Value = hx_main_guid.ToString();//HX_MAIN的ID,这儿验证是正确的 select * from hx_detail where parentid='6EE5CD73-DA6D-46F5-8946-902E5D0D281D'

sparaDetail = commDetail.Parameters.Add("@PARENTID", SqlDbType.NVarChar, 50);2
commDetail.Parameters["@PARENTID"].Value = hx_main_guid.ToString();//HX_MAIN的ID,这儿验证是正确的 select * from hx_detail where parentid='6EE5CD73-DA6D-46F5-8946-902E5D0D281D'3
hx_main_guid.ToString();//一定要ToString()
PARENTID
即使是GUID，也可以用SqlDbType.NVarChar, 50);来代替
只是下面一句赋值时要把guid转换成string型
hx_main_guid.ToString();
System.Guid guid_hx_detail = System.Guid.NewGuid();生成的是有种子的GUID
System.Guid guid_hx_detail = new Guid();生成的是0
