c# - 将文本文件解析为字典

我有一个具有数百个配置值的文本文件。配置数据的一般格式为“ Label：Value”。使用C＃.net，我想阅读这些配置，并在代码的其他部分中使用值。我首先想到的是，我将使用字符串搜索来查找标签，然后解析出标签后的值并将其添加到字典中，但是考虑到我必须搜索的标签/值的数量，这似乎很繁琐。我有兴趣听到一些关于可能执行此任务的体系结构的想法。我在样本文本文件的一小部分中包含了一些标签和值（如下）。一些注意事项：值并不总是数字的（如AUX序列号所示）。无论出于何种原因，文本文件都是使用空格（\ s）而不是制表符（\ t）格式化的。预先感谢您花费任何时间对此进行思考。

示范文本：

 AUX Serial Number:  445P000023       AUX Hardware Rev:           1

 Barometric Pressure Slope:     -1.452153E-02
 Barometric Pressure Intercept: 9.524336E+02

最佳答案

这是一个不错的小脑筋急转弯。我认为这段代码也许可以为您指明正确的方向。请记住，这会填充Dictionary<string, string>，因此不会将值转换为int等。另外，请原谅混乱（以及不良的命名约定）。根据我的思路，这是一篇简短的文章。

Dictionary<string, string> allTheThings = new Dictionary<string, string>();

public void ReadIt()
{
    // Open the file into a streamreader
    using (System.IO.StreamReader sr = new System.IO.StreamReader("text_path_here.txt"))
    {
        while (!sr.EndOfStream) // Keep reading until we get to the end
        {
            string splitMe = sr.ReadLine();
            string[] bananaSplits = splitMe.Split(new char[] { ':' }); //Split at the colons

            if (bananaSplits.Length < 2) // If we get less than 2 results, discard them
                continue;
            else if (bananaSplits.Length == 2) // Easy part. If there are 2 results, add them to the dictionary
                allTheThings.Add(bananaSplits[0].Trim(), bananaSplits[1].Trim());
            else if (bananaSplits.Length > 2)
                SplitItGood(splitMe, allTheThings); // Hard part. If there are more than 2 results, use the method below.
        }
    }
}

public void SplitItGood(string stringInput, Dictionary<string, string> dictInput)
{
    StringBuilder sb = new StringBuilder();
    List<string> fish = new List<string>(); // This list will hold the keys and values as we find them
    bool hasFirstValue = false;

    foreach (char c in stringInput) // Iterate through each character in the input
    {
        if (c != ':') // Keep building the string until we reach a colon
            sb.Append(c);
        else if (c == ':' && !hasFirstValue)
        {
            fish.Add(sb.ToString().Trim());
            sb.Clear();
            hasFirstValue = true;
        }
        else if (c == ':' && hasFirstValue)
        {

            // Below, the StringBuilder currently has something like this:
            // "    235235         Some Text Here"
            // We trim the leading whitespace, then split at the first sign of a double space
            string[] bananaSplit = sb.ToString()
                                     .Trim()
                                     .Split(new string[] { "  " },
                                            StringSplitOptions.RemoveEmptyEntries);

            // Add both results to the list
            fish.Add(bananaSplit[0].Trim());
            fish.Add(bananaSplit[1].Trim());
            sb.Clear();
        }
    }

    fish.Add(sb.ToString().Trim()); // Add the last result to the list

    for (int i = 0; i < fish.Count; i += 2)
    {
        // This for loop assumes that the amount of keys and values added together
        // is an even number. If it comes out odd, then one of the lines on the input
        // text file wasn't parsed correctly or wasn't generated correctly.
        dictInput.Add(fish[i], fish[i + 1]);
    }
}
