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 aList<string>
fileNames.
Iterate in the list usingforeach
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,
