C#获取yaml文件中父节点buildRelease下所有子节点为releaseID的值以及releaseID的兄弟节点buildEnvironment下所有子节点为buildSystem的值

在C#中，你可以使用`YamlDotNet`库来解析YAML文件。首先，你需要安装这个NuGet包。以下是处理这种情况的一种基本方法：

using YamlDotNet;
using YamlDotNet.Readers;
using YamlDotNet.Serialization;

// 假设有一个名为Config.yaml的文件内容如下：
// buildRelease:
//   - releaseID: value1
//   - releaseID: value2
// buildEnvironment:
//   - buildSystem: valueA
//   - buildSystem: valueB

public class Config
{
    public BuildRelease[] BuildRelease { get; set; }
    public BuildEnvironment[] BuildEnvironment { get; set; }
}

public class BuildRelease
{
    public string releaseID { get; set; }
}

public class BuildEnvironment
{
    public string buildSystem { get; set; }
}

// 加载并解析YAML文件
string yamlText = File.ReadAllText("Config.yaml");
var parser = new YamlParser();
var deserializer = new DeserializerBuilder().Build();
Config config = null;
try
{
    config = deserializer.Deserialize<Config>(new StringReader(yamlText));
}
catch (DeserializationException ex)
{
    Console.WriteLine($"Error parsing YAML: {ex.Message}");
}

// 获取所需数据
foreach (var release in config.BuildRelease)
{
    Console.WriteLine($"releaseID: {release.releaseID}");
}

foreach (var env in config.BuildEnvironment)
{
    Console.WriteLine($"buildSystem: {env.buildSystem}");
}
