Question

我想创建具有以字符串形式发送的属性的匿名对象。通过反射或其他方式（从字符串到匿名属性）可以做到这一点

 class Program
    {
        static void Main(string[] args)
        {

            object myobject = CreateAnonymousObjectandDoSomething("myhotproperty");
        }

        public static object CreateAnonymousObjectandDoSomething(string myproperystring)
        {
            //how can i create anonymous object from myproperystring
            return new { myproperystring = "mydata" }; //this is wrong !!
            // i want to create object like myhotproperty ="mydata"
        }
    }

您似乎正在尝试执行以下操作：

public static dynamic CreateAnonymousObjectandDoSomething(string mypropertystring)
{
    IDictionary<string, object> result = new ExpandoObject();
    result[mypropertystring] = "mydata";
    return result;
}

ExpandoObject基本上是一个字典，与dynamic一起使用时，可以像类型一样使用。

示例：

var test = CreateAnonymousObjectandDoSomething("example");
Console.WriteLine(test.example);
