如何将文件移动到另一个目录并将其文件名写入 SSIS 脚本任务的 C# 循环内的文件（创建和附加）？

Question

下面是循环源目录中所有*.tar.gz文件的代码。每个文件都与变量 dayOld_7 和 dayOld_14 进行比较。如果相等，则将 dayOld_7 标志或 dayOld_14 标志设置为 True。如果文件不是其中之一，则必须将文件移动到另一个目录并将其文件名写入文件 ListOfMovedFiles。我该怎么做？我是 C# 的新手。

    public void Main()
    {
        string dayOld_7 = DateTime.Now.AddDays(-7).ToString("yyyyMMdd") + ".tar";
        string dayOld_14 = DateTime.Now.AddDays(-14).ToString("yyyyMMdd") + ".tar";            
        string directoryPath = Dts.Variables["User::directoryPath"].Value.ToString();
        string[] sapFiles = System.IO.Directory.GetFiles(directoryPath, "*.tar.gz");
        string currFile;

        foreach (string fName in sapFiles)
        {
            FileInfo fNameInfo = new FileInfo(fName);
            currFile = Path.GetFileNameWithoutExtension(fNameInfo.FullName).ToString();

            if (currFile.Equals(dayOld_7))
            {
                Dts.Variables["User::Gzip_7"].Value = true;
            }
            else if (currFile.Equals(dayOld_14))
            {
                Dts.Variables["User::Gzip_14"].Value = true;
            }
            else if ( !(currFile.Equals(dayOld_7)) && !(currFile.Equals(dayOld_14)) )
            {
                //***What is the C# code to MOVE the file to a folder say C:/archive/ and write its filename to a file(create/append) ListOfMovedFiles.txt in the current directory?***
            }                 
        }
    }

从命名空间开始：

using System.IO;

要移动文件，很简单：

File.Move(sourceFilepath, destinationFilepath);

要写入文件，taken from MS:

try 
{

  //Pass the filepath and filename to the StreamWriter Constructor
  StreamWriter sw = new StreamWriter("C:\Test.txt");

  //Write a line of text
  sw.WriteLine("Hello World!!");

  //Write a second line of text
  sw.WriteLine("From the StreamWriter class");

  //Close the file
  sw.Close();
}
catch(Exception e)
{
  Console.WriteLine("Exception: " + e.Message);
}
finally 
{
  Console.WriteLine("Executing finally block.");
}

注意：您可以使用 CreateDirectory(dir) 创建一个目录，或者如果它已经存在，那么在命令中没有任何危害。
