如何在.NET Core上的动态表达构建器中转换为适当的数据类型？

Question

我有以下代码通过动态表达式处理过滤器。但是，如果数据类型是字符串，则可以正常工作，如果是号码或日期，我不知道该如何处理。.有人可以帮助

MemberExpression member = Expression.Property(param, filter.Name);
var propertyType = ((PropertyInfo)member.Member).PropertyType;
var converter = TypeDescriptor.GetConverter(propertyType);

filter.Value.Aggregate(
   (Expression)Expression.Constant(false),
   (acc, next) =>
       Expression.MakeBinary(
       ExpressionType.Or,
       acc, Expression.Equal(member, Expression.Constant(next))));

有效负载

{
  "pageFilters": [
    {
      "name": "firstName",
      "condition": "Equals",
      "value": [
        "john", "sam"
      ]
    }
  ]
}

{
  "pageFilters": [
    {
      "name": "age",
      "condition": "Equals",
      "value": [
        "30", "40" --> tried "value":[30,40] as well
      ]
    }
  ]
}
