C# anonymous type RuntimeBinderException

C# anonymous type RuntimeBinderException Anonymous types are more convenient to use in some scenarios. For example, a certain type will only be used once, so defining a Class at this time does not make much sense. You can use anonymous types to solve the problem, but when using it across projects , you still need to pay attention to avoid RuntimeBinderException problems Problem Description For example, we have a class library project of type netstandard2.0, which has a method like this: public static class StandardClass { public static dynamic Get() { return new { prop1 = “hello”, prop2 = 12 }; } } Then add the following example code to a net6.0 type console project using ClassLibrary1; try { var test = StandardClass.Get(); var prop1 = test.prop1; } catch (Exception e) { Console.WriteLine(e); throw; } At this time, when we try to run this console project to obtain the prop1 value, at this time, a RuntimeBinderException will be raised Solution Because anonymous types default to the access level of Internal. This means that there is no problem if you access this anonymous object through the Dynamic type in the same assembly, but if it crosses the assembly, RuntimeBinder will not…
