Question

我想查找将按以下格式计算百分比并给出结果的统计数据： WX GSA搜索％= GSA发生/ GSA发生+搜索发生+ ADVSearch发生* 100，即在这种情况下它应该给出如下：3/3 + 2 + 2 * 100 = 42.8

我尝试过的代码会出现每次搜索：

我的代码在这里：

 class Program
{
    static void Main()
    {
        System.IO.StreamReader myFile =
        new System.IO.StreamReader(@"C:\Users\karansha\Desktop\sample log.txt");
        string myString = myFile.ReadToEnd();
        Console.WriteLine(TextTool.CountStringOccurrences(myString, "WX Search"));   // WX Rule Based Search.
        Console.WriteLine(TextTool.CountStringOccurrences(myString, "WX GSA Search"));  // WX GSA Search.
        Console.WriteLine(TextTool.CountStringOccurrences(myString, "WX ADVSearch"));   //WX Form Based Search.
        // keep screen from going away
        // when run from VS.NET
        Console.ReadLine();
    }
}
public static class TextTool
{
    public static int CountStringOccurrences(string text, string pattern)
    {
        int count = 0;
        int i = 0;
        while ((i = text.IndexOf(pattern, i)) != -1)
        {
            i += pattern.Length;
            count++;
        }
        return count;
    }
}

您可以使用String.Format方法在.NET中格式化字符串。

int score = 50;
string formattedString = String.Format("My Score : {0}", score);
Console.WriteLine(formattedString); 
//My Score : 50

我真的不明白这个问题。你只是想计算公式并在控制台屏幕上显示它吗？如果你的意思是这里是你需要的代码：

static void Main()
{
    System.IO.StreamReader myFile =
    new System.IO.StreamReader(@"C:\Users\karansha\Desktop\sample log.txt");
    string myString = myFile.ReadToEnd();
    int wxSearchCount = TextTool.CountStringOccurrences(myString, "WX Search");   // WX Rule Based Search.
    int wxGsaSearchCount = TextTool.CountStringOccurrences(myString, "WX GSA Search");  // WX GSA Search.
    int wxAdvSearchCount = TextTool.CountStringOccurrences(myString, "WX ADVSearch");   //WX Form Based Search.

            double result = Convert.ToDouble(wxGsaSearchCount * 100) / Convert.ToDouble((wxGsaSearchCount + wxSearchCount + wxAdvSearchCount));

            Console.WriteLine("WX Search: {0}\nWX GSA Search: {1}\nWX ADVSearch: {2}\nResult: {3}",
                                wxSearchCount, wxGsaSearchCount, wxAdvSearchCount, result.ToString("0.00"));

    Console.ReadLine();
}

使用C sharp计算百分比统计数据？
