Entities objEntities = new Entities();
List<string> empName = new List<string>();
string ename = "";
var objList = (from i in objEntities.HCM_EMPLOYEE_DETAILS

推荐答案
尝试使用这个
Try using this
[System.Web.Services.WebMethod]
public static List<string> GetEmpName(string prefixText, int count)
而不是
instead of
[System.Web.Script.Services.ScriptMethod()]
[System.Web.Services.WebMethod]
public static List<string> GetEmpName(string prefixText)
