推荐答案

我认为这两个链接会对你有所帮助。但要记住一件事，组合大小您的其他文本文件，可能经常导致memoryOutExceptions.Good运气:)

I think these 2 links will help you a lot.But keep one thing in mind, the combined size of your other text files which may often cause memoryOutExceptions.Good luck :)

如果您在目录中搜索过，则将文件名放入列表< string> fileNames。

使用 foreach 循环在列表中迭代。



然后在foreach循环中使用以下基本文件复制（附加模式）代码。

If you have searched in the directory, Then put the file names into a List<string> fileNames.
Iterate in the list using foreach loop.

Then use the following basic file copying (in append mode) code inside that foreach loop.

using (Stream input = File.OpenRead(fileName))
using (Stream output = new FileStream("newFile.txt", FileMode.Append,
                                      FileAccess.Write, FileShare.None))
{
    input.CopyTo(output);
}
File.Delete("fileName.txt");

请找到copyto 方法以下。

Please find the copyto method below.

public static class StreamExtensions
{
    public static void CopyTo(this Stream input, Stream output)
    {
        if (input == null)
        {
            throw new ArgumentNullException("input)";
        }
        if (output == null)
        {
            throw new ArgumentNullException("output)";
        }
        byte[] buffer = new byte[8192];
        int bytesRead;
        while ((bytesRead = input.Read(buffer, 0, buffer.Length)) > 0)
        {
            output.Write(buffer, 0, bytesRead);
        }
    }
}

希望我已经回答了你的问题。 ：）

Hope i have answered your question. :)

试试这个：

String[] txtfiles = System.IO.Directory.GetFiles(ThePathToYourDir, "*.txt", System.IO.SearchOption.AllDirectories);

using (Stream output = new FileStream("YourCongregatedTextFile.txt", FileMode.Append,
                                      FileAccess.Write, FileShare.None))
{
    foreach (string file in txtfiles)
    {
       using (Stream input = File.OpenRead(file))
       {
           input.CopyTo(output); 
       }
    }
}

（我在解决方案文本框中将其写成纯文本，希望没有错别字......）



干杯，
