c# - 使用 C# 将文本文档分成多个部分

Question

我正在解析一个具有半已知重复结构的文本文件。有一个标题(1 行)、一个副标题(1 行或 2 行)和一个内容区域(任意行数)。文档中每一项的格式如下所示:

 =========================       Head Text 1=========================      SubHead Text1      SubHead Text2========================= Content Text Line 1 Content Text Line 2 ... Content Text Line 8=========================       Head Text 2=========================      SubHead Text1      SubHead Text2========================= Content Text Line 1 Content Text Line 2 ... Content Text Line 6

I would like each section to be inside a unique object, each with 3 sections... somethign like

section1.headsection1.subHeadsection1.contentsection2.headsection2.subHeadsection2.content

The only way I can think of accomplishing this involves a lot of if and while statements. Is there an efficient way of accomplishing this?

I originally tried writing some code in JScipt, but I'm reading a RTF file and C# provides an easy way of converting RTF to plain text. It didn't work very well, I kept skipping some dividers and would get an error at the end of the file.

page = new Array();

fso = new ActiveXObject("Scripting.FileSystemObject");
f = fso.GetFile("test.rtf");

is = f.OpenAsTextStream( forReading, -2 );

var count = 0;
while( !is.AtEndOfStream ){
   page[count] = is.ReadLine();
   count++; ;
}

is.Close();

WScript.Echo( page[0].text);

var item = [];

var section = 0;

var i = 0, k = 0;
while (i < page.length) {
item[k] = {};

    if (!page[i].indexOf("=====")) { 
        i++;    
        item[k].head = page[i];
        i+=2;
        while(page[i].indexOf("=====")) {   // WScript.Echo( "index = " + i + " "+ page[i] +"\n" + "Next index = " + (i+1) + " "+ page[i+1] +"\n" );
            item[k].subHead += page[i];
            i++;
        }

        k++;

    } 
    i++;
}

如果你想削减 IF，你可以实现一个状态模式，将每一行提交到当前状态。
