.net, c# ExpandoObject 构建动态类型。键值对Dictionary<string, object>转化成ExpandoObject

利用键值对Dictionary动态构建ExpandoObject,ExpandoObject中包含了与字典相同的键值对作为属性
```
using System;  
using System.Collections.Generic;  
using System.Dynamic;  
using System.Linq;  
  
public static class DictionaryExtensions  
{  
    public static ExpandoObject ToExpandoObject(this Dictionary<string, object> dictionary)  
    {  
        var expando = new ExpandoObject();  
        var expandoDict = (IDictionary<string, object>)expando;  
  
        // Copy all the key-value pairs from the dictionary to the expando object  
        foreach (var kvp in dictionary)  
        {  
            expandoDict[kvp.Key] = kvp.Value;  
        }  
  
        return expando;  
    }  
}  
  
// 示例用法  
class Program  
{  
    static void Main()  
    {  
        var dict = new Dictionary<string, object>  
        {  
            { "Name", "John Doe" },  
            { "Age", 30 },  
            { "IsActive", true }  
        };  
  
        dynamic expando = dict.ToExpandoObject();  
  
        Console.WriteLine(expando.Name); // 输出 "John Doe"  
        Console.WriteLine(expando.Age);  // 输出 30  
        Console.WriteLine(expando.IsActive); // 输出 True  
    }  
}
```
