如何使用 c 使用简单的字符串准确地实现键/值对最大值#-解网

问：

我有一个简单的字符串值行，其中包含以下内容。

logo Name raj mobile 9038874774 address 6-98 india bill auto generated

现在我正在尝试键/值对来实现我的详细信息和期望如下的对值输出

[0] Key: Name  value:Raj
[1] Key: Mobile value:9038874774
[2] Key: Address value:6-98 india

下面是试图实现要求的代码

string[] lines = new string[] { "logo Name raj mobile 9038874774 address 6-98 india bill auto generated" };
   
// Get the position of the empty sign within each line

var pairs = lines.Select(l => new { Line = l, Pos = l.IndexOf(" ") });

// Build a dictionary of key/value pairs by splitting the string at the empty sign
var dictionary = pairs.ToDictionary(p => p.Line.Substring(0, p.Pos), p => p.Line.Substring(p.Pos + 1));

// Now you can retrieve values by key:
var value1 = dictionary["Name"];

下面是调试器中的输出

文本字符串包含一些不需要的单词，例如自动生成的徽标和账单，不需要将这些单词添加到键/值对中。请建议如何准确地达到这个最大值，并使用terrasact OCR将从图像文件中获取的字符串数据转换为文本字符串

C# asp.net asp.net-core

private static readonly HashSet<string> _extractKeys = new() { "Name", "Mobile", "Address" };
private static readonly HashSet<string> _ignoredKeys = new() { "Bill" };

public static void Main(string[] args)
{
    var line = "logo Name raj Mobile 9038874774 Address 6-98 india Bill auto generated";
    var splitLine = line.Split(' ');

    var pairs = new Dictionary<string, string>();

    for (var i = 0; i < splitLine.Length; i++)
    {
        var candidateKey = splitLine[i];
        if (!_extractKeys.Contains(candidateKey))
        {
            continue;
        }

        var value = "";
        for (var v = i + 1; v < splitLine.Length; v++)
        {
            var candidateValuePart = splitLine[v];
            if (_ignoredKeys.Contains(candidateValuePart) || _extractKeys.Contains(candidateValuePart))
            {
                i = v - 1;
                break;
            }

            value = value + candidateValuePart + " ";
        }

        pairs.Add(candidateKey, value.Trim());
    }

    foreach (var kv in pairs)
    {
        Console.WriteLine("{0}: {1}", kv.Key, kv.Value);
    }
}

private static IDictionary<string, string> Parse(string input)
{
    var keys = ImmutableHashSet.Create(
        StringComparer.OrdinalIgnoreCase, "Name", "Mobile", "Address");
    var ignoredKeys = ImmutableHashSet.Create(StringComparer.OrdinalIgnoreCase, "Bill");
    var allKeys = keys.Union(ignoredKeys);
    var dict = new Dictionary<string, string>();

    string? currentKey = null;
    foreach (var word in input.Split(' '))
    {
        if (allKeys.TryGetValue(word, out var key))
        {
            if (key != null)
                dict[key] = "";
            currentKey = key;
        }
        else if (currentKey != null && dict.TryGetValue(currentKey, out var s))
            dict[currentKey] = (s + " " + word).Trim();
    }

    return new Dictionary<string, string>(dict.ExceptBy(ignoredKeys, kvp => kvp.Key));
}

在这里，我假设这也是一种应该被忽略的关键。"bill"
