我在下面有这段代码。获取数据并将数据属性设置为收集的值。
public struct TrblShootData
{
public List<string> Logins;
public IEnumerable<Hieracrhy> Hierarchy;
public IEnumerable<EmployeeTeam> EmpTeam;
}
public TrblShootData TroubleShootData
{
get;
private set;
}
class DataGetter
{
public void GetData(string FirstName, string LastName, string Login, string Email, bool isFirstName, bool isLastName, bool isLogin, bool isEmail)
{
List<string> logins = null;
IEnumerable<Hieracrhy> hier = null;
IEnumerable<EmployeeTeam> tmemp = null;
TrblShootData tsData = new TrblShootData();
queries q = BuildQuery(FirstName, LastName, Login, Email, isFirstName, isLastName, isLogin, isEmail);
if (q.isValidQueries)
{
DataContext1 mscDB = new DataContext1 ();
using (DataContext2 opsDB = new DataContext2 ())
{
tmemp = opsDB.ExecuteQuery<EmployeeTeam>(q.qryEmployeeTeam);
}
using (DataContext3 rptDB = new DataContext3 ())
{
hier = rptDB.ExecuteQuery<Hieracrhy>(q.qryHierarchy);
if (hier != null)
{
logins = hier.Select(s => s.SalesRepLogin).Distinct().ToList();
}
}
tsData.EmpTeam = tmemp.Select(r=>r);
tsData.Hierarchy = hier.Select(r => r);
tsData.Logins = logins.Select(r => r).ToList();
TroubleShootData = tsData;
}//if
}
}
从另一个班级我尝试这样做:
tshtr.GetData(txtFirstName.Text, txtLastName.Text, txtLogin.Text, txtEmail.Text, chkFirstName.Checked, chkLastName.Checked, chkLogin.Checked, chkEmail.Checked);
gvEmpTeams.DataSource = tshtr.TroubleShootData.EmpTeam;
gvHierarchy.DataSource = tshtr.TroubleShootData.Hierarchy;
gvEmpTeams.DataBind();
gvHierarchy.DataBind();
但是在 DataBind() 我收到一个错误,说我无法从封闭的阅读器中阅读。
我不明白为什么在我在 usings 中分配值后按上述设置属性时会引发此错误。所以我没有看到这是如何尝试使用封闭式阅读器。
谢谢你的帮助!
