Question

我查看了堆栈上的几个线程，但无法找到答案。

我有一个打开SQL连接的应用程序使查询比较字符串，然后输出中继项目的消息或在第二个应用程序中创建项目。

App每次都被卡在相同的值上＃J2; J2y7W0Q1Tn＆＃34;（这个项目存在于DB中），当我暂停它时Visual Studio告诉我connAm.Open（）;将运行next ...我正在使用using语句，但需要我的变量在此范围之外可用。

我厌倦了尽可能地简化这一点，但仍然包括可能需要的东西。

我需要使用包含connAM.Open（）的“using”语句来构造此调用的开头。在第二个“SQLReader”之前使用查询和比较循环启动。

using (SqlConnection connAM = new SqlConnection()) { // Added this above the query enclosing the second using statement. 
 connAM.ConnectionString = @"Data Source=s*****, 1433;Initial Catalog=*****;User id=*****;Password=*****;Trusted_Connection=False;MultipleActiveResultSets=true;Connection Timeout=200000";
                                            SqlCommand AccessCodeResult = new SqlCommand("SELECT [UsrAccessCode] FROM [AmSecureClose].[dbo].[PMTran] WHERE CompanyID = 3 AND UsrAccessCode LIKE '" + CleanTAccessCode + "'", connAM);
                                            connAM.Open();
                                            using (SqlDataReader AccessCodeResults = AccessCodeResult.ExecuteReader())
                                            {
