c# - 有没有办法循环这段代码，但是每次给变量一个不同的字符串？

问题描述

所以我有一些代码，工作得非常好，但只有一个实例，我想让它自己提供下一组变量，直到有一组不存在的变量......当你看到它会有意义编码。该代码只是定位并告诉字符位置并将其从原始文本中摘录出来。

所以我尝试循环它，这很容易，但我不知道如何每次都更改实例

//For comparison text
string ImpureCText = "I was very <title> proud of my  my my nickname throughout high school. but today I couldn’t be .any ¡ different to what my </title> nickname was kdrlfmb ksd.f gaeks fak<p1> helllo this is a pharagraph that has been been compressed down by irrelvant words and put into a list so i can compare how many times it pops up up up in the article or in tho</p1>.";// insert text file here
string parastart = "<p1>";  // need to make this so it can change to <p2>. <p3>..etc:
bool b = ImpureCText.Contains(parastart);
string paraend = "</p1>";       // need to make this so it can change to </p2>, </p3>..etc:
bool l = ImpureCText.Contains(paraend);
if (b && l)
{                                                                                                               
    int index1 = ImpureCText.IndexOf(parastart);
    int index2 = ImpureCText.IndexOf(paraend);
    if (index1 >= 0)                                                                                //locates char position of start of pharagraph
        Console.WriteLine("'{0} begins at character position {1}", parastart, index1 + 1 );
    Console.WriteLine("'{0} begins at character position {1}", paraend, index2 + 1);

    //string PurePCText = ImpureCText.Substring(index1, index2);

    string PurePCText = ImpureCText.Substring(index2-index1);
    Console.WriteLine("Over here--"+ PurePCText);

所以它基本上会通过 , , ,... 循环这段代码，直到被识别为不存在

解决方案

制作一个包含要打印的开始和结束标签的数组：

var startTags = new[] { "<p1>", "<p2>", ... };
var endTags = new[] { "</p1>", "<p2>", ... };

for (var i = 0; i < startTags.Length; i++)
{
    var startTag = startTags[i];
    var endTag = endTags[i];

    // Do tag stuff
}

但是如果你有一个索引，你可以使用它在循环中构建标签字符串：

for (var i = 1; i <= 8; i++)
{
    var startTag = $"<p{i}>";
    var endTag = $"</p{i}/>";

    // Do tag stuff
}
