将用户定义的规则转换为 C# 表达式

问：

我有一组由用户定义的规则，我需要帮助将其转换为可以使用 linq 执行的规则表达式。

下面是示例 JSON 有效负载

{
  "Rules": [
    {
      "Field": "year",
      "Condition": "Equals",
      "Value": "2020",
      "Operator": "And"
    },
    {
      "Field": "color",
      "Condition": "NotEquals",
      "Value": "black",
      "Operator": "And"
    },
    {
      "Field": "amount",
      "Condition": "GreaterThan",
      "Value": "100",
      "Operator": "Or"
    },
    {
      "Field": "country",
      "Condition": "NotEquals",
      "Value": "US"
    }
  ]
}

要查询的数据如下表所示

在应用规则之前，可以将这些内容加载到列表中。该规则应该一次评估一个用户。

我已将JSON转换为下面的模型，但我无法弄清楚如何实现规则

public class BusinessRule
{
    public List<RuleModel> Rules { get; set; }
}

public class RuleModel
{
    public string Field { get; set; }
    public RuleConditionEnum Condition { get; set; }
    public string Value { get; set; }
    public RuleOperatorEnum? Operator { get; set; }
}

public enum RuleConditionEnum
{
    Equals = 1,
    NotEquals,
    Contains,
    NotContains,
    StartsWith,
    EndsWith,
    GreaterThan,
    LessThan,
    GreaterOrEqual,
    LessOrEqual
}

public enum RuleOperatorEnum
{
    And = 1,
    Or
}

我将不胜感激示例代码的任何帮助。
