C#脚本问题-字符串不能正确地分隔成列表？

我正在尝试将纯文本文件加载到列表（列表（字符串））中，由EndTextBlock（到列表中）或EndDialogBlock（到列表（列表）)分隔。每个对话框块可以是不同的长度。

我有一个简单的读取文件行，它读取txt文件的每一行，并将每一行作为一个新项添加到TXTDialogFileList中。下面的代码是我试图整理原始数据并创建双列表的地方。

//loop to increment the list's counter
for (int i = 0; i < TXTDialogFileList.Count; i++)   
{
    DialogBlock = new List<string> ();

    bool NextRun = false;
    do
    {   //do-while loop to merge multiple lines into 1 slot in the list
        //DialogBlock = new List<string> ();

        if ( (i + 1) < TXTDialogFileList.Count)
        {
            if (   TXTDialogFileList[i+1] == "EndDialogBlock" 
                || TXTDialogFileList[i+1] == "EndTextBlock"     )
            {
                //line break removal to next in list
                //TXTDialogFileList[i+1].Remove(TXTFileList[i+1]);
                //print (TXTDialogFileList[i]);
                //print (RunCounter + " " + (i + 1));

                DialogBlock.Add (TXTDialogFileList[i]);

                //DialogConvertedList[RunCounter].Add (TXTDialogFileList[i]);
                if (TXTDialogFileList[i+1] == "EndDialogBlock")
                {
                    //only increment counter for converted list if it's end dialog
                    RunCounter ++;  
                    DialogConvertedList.Add (DialogBlock);
                    NextRun = false;
                }
                else if (TXTDialogFileList[i+1] == "EndTextBlock")
                {
                    DialogConvertedList.Add (DialogBlock);
                    NextRun = true;
                    //DialogBlock = new List<string>();
                }
                TXTDialogFileList.Remove(TXTDialogFileList[i+1]);
            }

            else
            {
                //merging next line to current line in list (line break in between)
                TXTDialogFileList[i] = TXTDialogFileList[i] 
                                        + '\n' + TXTDialogFileList[i+1];
                TXTDialogFileList.Remove(TXTDialogFileList[i+1]);
                NextRun = true;
            }
        }
        else
        {
            //no more lines in file
            NextRun = false;
        }
    } while ((NextRun == true));
}

代码中有一个问题，我似乎找不到如何修复它。现在我得到的结果是:textbox1输出text1，textbox2输出text1+text2，textbox3输出text1+text2+text3，以此类推。

在将ConvertedList列表添加到DialogBlock列表之后，我再次尝试将DialogBlock声明为一个新列表，但这最终导致Text1之后的所有内容完全消失。

感谢任何帮助！

看看我是否理解你的目标。下面是我的示例文本：

The first line of text
The second line of text
EndTextBlock
The third line of text
The fourth line of text
EndTextBlock
The fifth line of text
The sixth line of text
EndDialogBlock
The seventh line of text
The eight line of text
EndTextBlock
EndDialogBlock
The ninth line of text
The tenth line of text
EndTextBlock
The eleventh line of text
The twelfth line of text
EndDialogBlock

下面是一些处理它的代码。我保留了您的变量名txtDialogFileList，但我认为这可能会引起误解。我更改了许多其他代码，因为它们引用了代码段之外的元素：

    List<String> TXTDialogFileList = new List<String>();

    StreamReader sr = new StreamReader(@"sampletext");
    while (sr.Peek() >= 0)
    {
        TXTDialogFileList.Add(sr.ReadLine());
    }
    sr.Close(); 

    var currentList = new List<String>();   
    var resultList = new List<List<String>>();  
    var currentLines = "";

    foreach (String line in TXTDialogFileList)
    {
        switch (line)
        {
            case "EndTextBlock":
                currentList.Add(currentLines);
                currentLines="";
                break;
            case "EndDialogBlock":
                if (currentLines.Length > 0) currentList.Add(currentLines); // assuming implicit EndTextBlock before EndDialogBlock
                resultList.Add(new List<String>(currentList)); // list<string> added by reference so make sure it is a new list before it is cleared on next line
                currentList.Clear(); 
                currentLines="";
                break;
            default:
                currentLines += line + "\n";
                break;  
        }
    }

    // Output the List<List<String>> to show results are correct
    foreach (var textBlock in resultList)
    {
        Console.WriteLine("Start DialogBlock");
        foreach(var text in textBlock)
        {
            Console.WriteLine("Start TextBlock");
            Console.Write(text);
        }
    }

    Console.Read();

即使我误解了你的确切目标，我认为你需要注意的是：

使用foreach循环。更容易阅读。
使用switch语句。更容易阅读，我想适合你的需要。
要小心将列表添加到列表中。修改
以后添加的列表时，就是修改添加的列表。换句话说，它们是通过引用添加的。
