SQL 异常 - 与网络相关或特定于实例。SQL Express“它可以在我的机器上运行”问题

Question

EDIT: It only took a week but I eventually found out the issue, primarily due to pure luck and another error with a more specific fix. The issue was with the connStr I had made, which for some reason on this machine gave me the error randomly of "System.ArgumentException: Keyword not supported: 'datasource'." during runtime. I then found out a fix for that was to rename the connStr as follows:

 connStr = @"server = (server name); Initial Catalog = AutoTestDB; Integrated Security = true";

Should you have this error as I have, try that method of connection. END EDIT

I'm currently working on Automated Testing using Katalon Automated Testing, essentially Selenium for Chrome, and whenever I'm attempting to add the results of the test to our Test Results Database the SQL Exception "A network-related or instance-specific error occurred while establishing a connection to SQL Server. " keeps popping up. TCP/IP is open, as is firewall and remote connections, and I have the SQL-SMS open and running while I run the database with the SQL connection.

However it only happens whenever I'm using a certain machine to access the database which is stored within the machine itself, as it is with every other machine that I use and they all work perfectly fine. The only difference I can think of for this machine is that it uses SQL Express while all the others that I use have the full version of Microsoft SQL-SMS-17.

It's a genuine case of "It works on my machine", except with the caveat that it works on several others and even across different users as we are all working on this automated testing, this machine is the lone exception for this code not working, with the only difference being that it uses SQL Express which should be accounted for with the \\SQLExpress.

C# code with SQL connetions to edit the values into an already made table within the database.

public void testDBAdd(String testName, Boolean pass, String testComment)
    {
        SqlConnection con;
        SqlDataAdapter daAutoTest;
        DataSet dsAutoTestDB = new DataSet();
        SqlCommandBuilder cmdBAutoTest;
        String connStr, sqlAutoTest;

        connStr = @"datasource = .\\sqlexpress; Initial Catalog = AutoTestDB; Integrated Security = true";
        con = new SqlConnection(connStr);

        sqlAutoTest = @"SELECT * FROM TestResults";
        daAutoTest = new SqlDataAdapter(sqlAutoTest, connStr);
        cmdBAutoTest = new SqlCommandBuilder(daAutoTest);
        daAutoTest.FillSchema(dsAutoTestDB, SchemaType.Source, "AutoTest");
        daAutoTest.Fill(dsAutoTestDB, "AutoTest");

        foreach (DataRow drAutoTest in dsAutoTestDB.Tables["AutoTest"].Rows)
        {
            if (pass == true && drAutoTest["testName"].ToString() == testName)
            {
                drAutoTest.BeginEdit();

                drAutoTest["testName"] = testName;
                drAutoTest["testResult"] = 1;
                drAutoTest["testComment"] = testComment;

                drAutoTest.EndEdit();
                daAutoTest.Update(dsAutoTestDB, "AutoTest");
            }
            else if (pass == false && drAutoTest["testName"].ToString() == testName)
            {
                drAutoTest.BeginEdit();

                drAutoTest["testName"] = testName;
                drAutoTest["testResult"] = 0;
                drAutoTest["testComment"] = "Exception: " + testComment;

                drAutoTest.EndEdit();
                daAutoTest.Update(dsAutoTestDB, "AutoTest");
            }
        }
    }

Code which runs the actual test and gathers if it has passed or failed due to the presence of certain elements, in this case is a certain page displayed when the user logs in and clicks a button.

public void settingTest<TestNumber>()
    {
        IWebDriver driver = new ChromeDriver();
        ChromeOptions options = new ChromeOptions();
        options.AddArguments("--start-maximized");
        driver = new ChromeDriver(options);
        String testName = "<Test Number>", testComment = "";
        Boolean pass = false;
        try
        {
            settingsLogin(driver);
            settingsClick(driver);

            Assert.IsTrue(driver.FindElement(ElementLocator).Displayed);

            if (driver.FindElement(ElementLocator).Displayed == true)
            {
                testComment = "Pass";
                pass = true;
                testDBAdd(testName, pass, testComment);
            }
        }
        catch (Exception ex)
        {
            testComment = "" + ex.TargetSite + "" + ex.Message;
            testDBAdd(testName, pass, testComment);
        }
        finally
        {
            driver.Close();
        }
    }

只花了一周的时间，但我最终发现了这个问题，主要是由于纯粹的运气和另一个更具体的修复错误。问题出在我制作的 connStr 上，由于某种原因，它在这台机器上随机给出了错误“System.ArgumentException：不支持关键字：'数据源'”。在运行时。然后我发现解决方法是重命名 connStr，如下所示：

 connStr = @"server = (server name); Initial Catalog = AutoTestDB; Integrated Security = true";
