C#实现获取yaml文件中buildReleases父节点下所有的releaseID节点值(整型)以及其兄弟节点buildEnvironmentsbuildSystem的buildSystem子结点的值

在C#中，要从YAML文件中提取特定结构的数据，你可以使用一些开源库如`YamlDotNet`来解析YAML内容。首先，你需要添加YamlDotNet的NuGet包到你的项目中：

<PackageReference Include="YamlDotNet" Version="8.0.4" />

然后，你可以创建一个解析函数来读取并提取所需的值。假设YAML文件结构如下：

buildReleases:
  - releaseID: 1
    buildEnvironments:
      - buildSystem:
          buildSystem: "GitLab CI"
  - releaseID: 2
    buildEnvironments:
      - buildSystem:
          buildSystem: "Jenkins"

你可以这样做：

using System;
using YamlDotNet.Reading;

public static class YamlParser
{
    public static void ExtractValues(string yamlFilePath)
    {
        var reader = new YamlStream();
        if (!reader.LoadFromFile(yamlFilePath))
            throw new Exception($"Failed to load YAML file: {yamlFilePath}");

        var doc = reader.Documents[0];
        foreach (var release in doc.RootNode.ChildrenNamed("buildReleases"))
        {
            int releaseId = (int)release.Children["releaseID"].Value;
            string buildSystem = release.Children["buildEnvironments"][0].Children["buildSystem"]["buildSystem"].Value.ToString();

            Console.WriteLine($"Release ID: {releaseId}, Build System: {buildSystem}");
        }
    }
}

要使用这个函数，传入你的YAML文件路径：

string filePath = "path_to_your_yaml_file.yaml";
YamlParser.ExtractValues(filePath);
