我正在生成一个文件流并将其包装在缓冲流阅读器中。然后我用读取线一次消耗一条流。在 X 行/字节数之后,我遇到了堆栈溢出异常。递归调用方法似乎不是问题,因为它可以毫无问题地处理较小的文件。我希望我在这里忽略了一些简单的事情。在这里发布整个片段有很多逻辑,但这是要点......

Instantiates a static stream reader //
{    
    using (FileStream fs = File.Open(filename, FileMode.Open, FileAccess.Read,
    FileShare.Read))
    using (BufferedStream bs = new BufferedStream(fs))
    using (reader = new StreamReader(bs))

     InitializeRecord(reader) // passes reader in
}

InitializeRecord(StreamReader reader)
{  
    //Makes some determinations whether to take in the first line or skip to first    header record... This is working fine. Initializes first line = reader.ReadLine()
    // Calls the first method to generate the header output which in turns calls the LineReader Method to consume the next line.
}

LineReader()
{ // Main loop for iterating over lines where stackoverflow occurs
    while (!reader.EndOfStream)
    {
        string prev_line = line;
        line = reader.ReadLine(); // StackOverFlow occurs here only on larger files / # of bytes read        
        VerifyLine(line,prev_line);
    }
}

VerifyLine(string line)
{ 
    // Does some checking on the line and calls output methods for each record type which in turn calls LineReader which LineReader exits when the endofstream is reached. 
    //But is blowing up prior to reaching the end of the stream.  By writing the lines out to disk as it iterates it writes a replica of the stream perfectly until the stack overflow occurs. 
    //This is only the difference of anything greater than a 5 MB file. Some of these records are hitting 9 million characters. I tried increasing the buffer size without luck.

递归调用方法似乎不是问题,因为它可以毫无问题地处理较小的文件

但是您是说它会在更大的文件上爆炸,对吗?对我来说,这听起来像是你的递归有问题。反正有没有递归执行你的操作?我想在 verifyLine 方法中看到更多代码。
