我有一段代码专用于创建多个表，但它创建第一个然后抛出异常，但该异常不包含任何内容，其空白。这里是我的代码：sql只创建一个表
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然后停止。谁能帮忙？
PS在之前有人说为什么不只是在VS中创建数据库，因为我已经尝试过，并且他们在我的计算机上工作正常，但是当我创建安装文件进行部署时，文件夹变得混乱起来，程序难道不识别DB再
任何错误消息？您是否在执行代码时运行SQL Profiler？当你说“停止”时意味着什么 - 像代码控制暂停，应用程序崩溃？ –
SQL事件探查器？没听说过，听起来很有用。它不冻结，它只是停留在该行，并打开所有的说和做时应该打开的形式 –
不幸的[运气不好]（http://stackoverflow.com/questions/225121/profiler-for-sql- ce），我的建议是把'table1.ExecuteNonQuery（）;'放在Try-Catch中，看它是否弹出提示。祝你好运！ –
