c# - 如何为匿名对象的属性设置值？

Question

例如，这是我的代码:

var output = new
{
    NetSessionId = string.Empty
};

foreach (var property in output.GetType().GetProperties())
{
    property.SetValue(output, "Test", null);
}

发生异常:“找不到属性集方法”。我想知道如何创建具有可设置属性的匿名类型。

谢谢。

匿名类型属性是只读的，不能设置。

Anonymous types provide a convenient way to encapsulate a set of read-only properties into a single object without having to explicitly define a type first. The type name is generated by the compiler and is not available at the source code level. The type of each property is inferred by the compiler.
