Cシャープを介してストアドプロシージャを呼び出していますが、奇妙な理由で2回目の実行でタイムアウトします。
ストアド プロシージャを呼び出すコード:
private void LoadData()
{
BackgroundWorker bw = new BackgroundWorker();
bw.DoWork += new DoWorkEventHandler(bw_LoadData);
bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_LoadDataComplete);
Busy.IsBusy = true;
Busy.BusyContent = "Loading Data";
bw.RunWorkerAsync();
}
void bw_LoadData(object sender, DoWorkEventArgs e)
{
SqlConnection con = new SqlConnection(Logic.GetConnectionString());
con.Open();
SqlCommand com = new SqlCommand("spGetUserData", con);
com.CommandType = System.Data.CommandType.StoredProcedure;
com.Parameters.Add(new SqlParameter("@UID", uid));
//Timeouts here on the second run
SqlDataReader readUserData = com.ExecuteReader();
while (readUserData.Read())
{
origname = readUserData[0].ToString();
origemail = readUserData[1].ToString();
origcontact = readUserData[2].ToString();
origadd1 = readUserData[3].ToString();
origadd2 = readUserData[4].ToString();
origstate = readUserData[5].ToString();
origcity = readUserData[6].ToString();
origzip = readUserData[7].ToString();
origcountry = readUserData[8].ToString();
}
con.Close();
con.Dispose();
e.Result = "OK";
}
void bw_LoadDataComplete(object sender, RunWorkerCompletedEventArgs e)
{
Busy.IsBusy = false;
txtFullName.Text = origname;
txtEmail.Text = origemail ;
txtContact.Text= origcontact;
txtAdd1.Text= origadd1;
txtAdd2.Text= origadd2 ;
txtState.Text= origstate;
txtCity.Text= origcity;
txtZip.Text = origzip;
cboCountry.SelectedItem = origcountry;
}
ウィンドウロードイベント中の最初のメソッド呼び出し..期待どおりに動作します。
private void Window_Loaded_1(object sender, RoutedEventArgs e)
{
LoadData();
}
タイムアウトが発生した 2 番目のメソッド呼び出し。
void bw_ChangeEmailComplete(object sender, RunWorkerCompletedEventArgs e)
{
if (e.Result.ToString() == "OK")
{
Busy.IsBusy = false;
MessageBox.Show("The Email Address was changed successfully", "Message", MessageBoxButton.OK, MessageBoxImage.Information);
}
else
{
Busy.IsBusy = false;
MessageBox.Show("An Unexpected Error occured or email already exist", "Error", MessageBoxButton.OK, MessageBoxImage.Error);
}
LoadData();
}
そして最後にストアドプロシージャ
Create Proc [dbo].[spGetUserData]
@UID varchar(50)
AS
Select FullName,Email,Contact,Address1,Address2,State,City,Zip,Country,SubDate,SID
FROM Users
Where UID = @UID
アップデート
これを試してもまだ動作せず、データリーダーを手動で破棄する
using (SqlConnection con = new SqlConnection(Logic.GetConnectionString()))
{
using (SqlCommand com = new SqlCommand("spGetUserData", con))
{
com.CommandType = System.Data.CommandType.StoredProcedure;
com.Parameters.Add(new SqlParameter("@UID", uid));
con.Open();
using (var readUserData = com.ExecuteReader())
{
while (readUserData.Read())
{
origname = readUserData[0].ToString();
origemail = readUserData[1].ToString();
origcontact = readUserData[2].ToString();
origadd1 = readUserData[3].ToString();
origadd2 = readUserData[4].ToString();
origstate = readUserData[5].ToString();
origcity = readUserData[6].ToString();
origzip = readUserData[7].ToString();
origcountry = readUserData[8].ToString();
}
}
}
}
