C# 根据文件的邮政编码值创建目录并使用 System.IO、System.Data 和传输文件CSV阅读器

Question

现有应用程序：我有一个 C# 应用程序，它运行搜索并获取匹配的引导文件并将它们放入特定的目录中。

添加功能：让系统检查文件的邮政编码是否存在子目录，如果不存在则创建它，然后我希望将文件传输到相应的目录中。

问题：现在，没有任何文件正在传输，也没有任何子目录正在创建。什么也没发生。是语法问题还是我调用错误？？？

请帮忙！

这是我添加的内容：

            string targetzipdir = m_sc.get_TargetPath() + "\\" + ZIP;
            // If the zip code subdirectory doesn't exist, create it.

            if (!Directory.Exists(targetzipdir))
            {
                 Directory.CreateDirectory(targetzipdir);
            } 

         private void TransferFile(string sourceDir, string filename, string ZIP)     
         { 
            string targetFileAndPath = m_sc.get_TargetPath() + "\\" + ZIP + "\\" + fullFileName;

这是 SearchProcess.cs 文件中的更多代码，以了解更大的情况（保留了一些内容）：

    public void Run()
    {
        m_sc = (SearchCriteria)m_form.Invoke(m_form.m_DelegateGetSearchCriteria);
        // Display parameters
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Corp: " + m_sc.get_Corp() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on OrderNumber: " + m_sc.get_OrderNumber() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Campaign: " + m_sc.get_Campaign() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on City: " + m_sc.get_City() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on State: " + m_sc.get_State() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Zip: " + m_sc.get_Zip() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Source Path: " + m_sc.get_SourcePath() });
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] { "Search on Target Path: " + m_sc.get_TargetPath() });

        DirSearch(m_sc.get_SourcePath());

        // Make asynchronous call to main form
        // to inform it that thread finished
        m_form.Invoke(m_form.m_DelegateThreadFinished, null);
    }

            for (int colNum = 0; colNum < expectedTypes.Count; colNum++)
            {
            if (m_sc.get_SearchOR().Equals(true))
                // Check for the Zip match
                if (m_sc.get_Zip() != "" && ZIP.Contains(m_sc.get_Zip()) == true)
                {
                    found = true;

                    string targetzipdir = m_sc.get_TargetPath() + "\\" + ZIP;
                    // If the zip code subdirectory doesn't exist, create it.

                    if (!Directory.Exists(targetzipdir))
                    {
                        Directory.CreateDirectory(targetzipdir);
                    } 

                }     // ending if (m_sc.get_SearchOR().Equals(true))
            }         //ending for loop  

    private void TransferFile(string sourceDir, string filename, string ZIP)
    {
        string fullFileName = filename + ZIP + ".pdf";
        string fullFileNameAndPath = sourceDir + "\\" + fullFileName;

        //copy matching source file into the specified subdirectory based on zip
        string targetFileAndPath = m_sc.get_TargetPath() + "\\" + ZIP + "\\" + fullFileName;
        // Copy the file if the source file exists
        if (File.Exists(fullFileNameAndPath))
        {
            m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"COPYING FROM: " + fullFileNameAndPath});
            m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"TO: " + targetFileAndPath});
            // Do the copy, overrite the target file if it exists
            File.Copy(fullFileNameAndPath, targetFileAndPath, true);
        }
        else
        {
            m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"Source file does not exist: " + fullFileNameAndPath});
        }
        m_form.Invoke(m_form.m_DelegateAddString, new Object[] {""});
    }

感谢您的查看！任何想法将不胜感激！ :)

我发现问题了！我在错误的位置创建目录的代码。它位于邮政编码匹配的 If 语句下，仅当邮政编码匹配并且邮政编码是搜索中的可选字段时才会执行。我将所有代码移至 TransferFile 方法下，并且运行良好。此外，数据的源目录必须指向 C:\Documents and Settings\bmccarthy\Desktop\sourcedir 并且文件必须采用特殊格式，位于该目录的子目录下
C:\Documents and Settings\bmccarthy\Desktop\sourcedir\AMLDailyHotLeads20101001

这是重写的代码：

            // Copy the file if ANY of the search criteria have been met
            if (found)
            {

                m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"FOUND: Order_No: " + Order_No +

                                                                        " MailerCode: " + MailerCode +
                                                                        " AgentID: " + AgentID +
                                                                        " City: " + City +
                                                                        " State: " + State +
                                                                        " ZIP: " + ZIP});
                //passes values to TransferFile 
                TransferFile(directory, barcode, AgentID, ZIP);
            }
        } // end for that finds each matching record 

    }

    // find and copy the file to the target directory string ZIP

            string targetzipdir = m_sc.get_TargetPath() + "\\" + AgentID + "\\" + ZIP;

            // If the given lead's zip code subdirectory doesn't exist, create it.
            if (!Directory.Exists(targetzipdir))
            {
                Directory.CreateDirectory(targetzipdir);
            }

            targetFileAndPath = m_sc.get_TargetPath() + "\\" + AgentID + "\\" + ZIP + "\\" + fullFileName;

        // Copy the file if the source file exists
        if (File.Exists(fullFileNameAndPath))

            m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"TO: " + targetFileAndPath});

            // Copy the file and over-write the target file if it exists
            File.Copy(fullFileNameAndPath, targetFileAndPath, true);
        }
        else
        {
            m_form.Invoke(m_form.m_DelegateAddString, new Object[] {"Source file does not exist: " + fullFileNameAndPath});
        }

    }
