我有一段代碼專用於創建多個表，但它創建第一個然後拋出異常，但該異常不包含任何內容，其空白。這裏是我的代碼：sql只創建一個表
string connectionString = "DataSource=\"EventControl.sdf\"";
SqlCeEngine en = new SqlCeEngine(connectionString);
en.CreateDatabase();
string createTable = "CREATE TABLE Login (userName nvarchar(50), UserType nvarchar(10), Salt nvarchar(100), Hash nvarchar(100))";
string connection = "Data Source =\"EventControl.sdf\"";
SqlCeConnection connexion = new SqlCeConnection(connection);
SqlCeCommand table = new SqlCeCommand(createTable, connexion);
try
{
connexion.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
table.ExecuteNonQuery();
connexion.Close();
string createTable1 = "CREATE TABLE Logs (LogNo nvarchar(5), LoggedBy nvarchar(20), DateAndTime nvarchar(20), Callsign nvarchar(20), Category nvarchar(20), SubCategory nvarchar(20), Escalated nvarchar(15), Summary nvarchar(MAX), Complete nvarchar(10))";
string connection1 = "Data Source =\"EventControl.sdf\"";
SqlCeConnection connexion1 = new SqlCeConnection(connection1);
SqlCeCommand table1 = new SqlCeCommand(createTable1, connexion1);
try
{
connexion1.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
table1.ExecuteNonQuery();
connexion1.Close();
string createTable2 = "CREATE TABLE Sites (SiteName nvarchar(100),SiteAddress nvarchar(100),PersonInCharge nvarchar(100))";
string connection2 = "Data Source =\"EventControl.sdf\"";
SqlCeConnection connexion2 = new SqlCeConnection(connection2);
SqlCeCommand table2 = new SqlCeCommand(createTable2, connexion2);
try
{
connexion2.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
table2.ExecuteNonQuery();
connexion2.Close();
string createTable3 = "CREATE TABLE Categories (Category nvarchar(50), SubCategory nvarchar(50))";
string connection3 = "Data Source =\"EventControl.sdf\"";
SqlCeConnection connexion3 = new SqlCeConnection(connection3);
SqlCeCommand table3 = new SqlCeCommand(createTable3, connexion3);
try
{
connexion3.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
table3.ExecuteNonQuery();
connexion3.Close();
string createTable4 = "CREATE TABLE Callsigns (StaffName nvarchar (50), Callsign nvarchar(50))";
string connection4 = "Data Source =\"EventControl.sdf\"";
SqlCeConnection connexion4 = new SqlCeConnection(connection4);
SqlCeCommand table4 = new SqlCeCommand(createTable4, connexion4);
try
{
connexion4.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
table4.ExecuteNonQuery();
connexion4.Close();
string createTable5 = "CREATE TABLE Events (EventName nvarchar(100), EventLocation nvarchar(100), PersonInCharge nvarchar(100))";
string connection5 = "Data Source =\"EventControl.sdf\"";
SqlCeConnection connexion5 = new SqlCeConnection(connection5);
SqlCeCommand table5 = new SqlCeCommand(createTable5, connexion5);
try
{
connexion5.Open();
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
table5.ExecuteNonQuery();
connexion5.Close();
它得到table1.ExecuteNonQuery然後停止。誰能幫忙？
PS在之前有人說爲什麼不只是在VS中創建數據庫，因爲我已經嘗試過，並且他們在我的計算機上工作正常，但是當我創建安裝文件進行部署時，文件夾變得混亂起來，程序難道不識別DB再
任何錯誤消息？您是否在執行代碼時運行SQL Profiler？當你說「停止」時意味着什麼 - 像代碼控制暫停，應用程序崩潰？ –
SQL事件探查器？沒聽說過，聽起來很有用。它不凍結，它只是停留在該行，並打開所有的說和做時應該打開的形式 –
不幸的[運氣不好]（http://stackoverflow.com/questions/225121/profiler-for-sql- ce），我的建議是把'table1.ExecuteNonQuery（）;'放在Try-Catch中，看它是否彈出提示。祝你好運！ –
