How to Pass Type as Parameter to Controller for XML Deserialization in C#
In C# , it’s common to work with data serialized in XML format, especially when you're building applications that exchange information over the web. However, you may run into problems when trying to pass types as parameters to a controller for XML deserialization. Today, we'll walk you through a common issue that developers face and provide a clear, workable solution.
The Problem
The challenge arises when you attempt to deserialize an XML string using a type that has been passed to a controller method. The key problem is that if the type being passed isn't accessible (i.e., it isn't public), you will receive an error:
System.RuntimeType is inaccessible due to its protection level. Only public types can be processed. This error prevents your application from effectively retrieving the data you're trying to work with.
Example Scenario
Suppose you have a class named ProjectReportDto, which holds information about project reports. You also have an XML string that represents an array of these objects. Your goal is to deserialize this XML into a list of ProjectReportDto objects in your controller.
Here’s what the ProjectReportDto class looks like:

And here’s the XML string you would like to deserialize:

The Solution
The solution to the error lies in how you retrieve the type name for List<ProjectReportDto>. You are currently using GetType() on the type itself, which does not yield a public type name. However, here's how you can rectify this situation.
Step-by-step Guidance
Change Your Type Retrieval Method: Instead of using GetType().FullName, use the FullName property directly on the List<ProjectReportDto> type.

Instantiate the XmlSerializer: After successfully obtaining the type name, you can then proceed with instantiating the XmlSerializer using this string.

Carry out the Deserialization
You can now carry out the deserialization as intended. Because the type is now recognized as public, you should no longer encounter the access error. Make sure your XML string and the destination class schema correctly align for successful data mapping.
Conclusion
Passing types as parameters to your controller for XML deserialization in C# doesn’t have to be a headache. By using the FullName property directly on your type, you enable the serializer to access the public type, leading to successful deserialization. Remember, understanding how types and their visibility work in .NET will save you lots of time and effort down the road.
