数据源是无效类型.它必须是IListSource,IEnumerable或IDataSource.绑定网格视图时显示错误

var list = dal.GetEmployeebyName(name);
GridViewEmployee.DataSource = list;
GridViewEmployee.DataBind();

我有查询

public EmployeeInfo GetEmployeebyName(String name)
{
    using (var context = new HRMSEntities())
    {
        return context.EmployeeInfo.FirstOrDefault(e => e.FName == name);
    }
}
