[mono] expression Cannot box IsByRefLike type 'System.ReadOnlySpan`1'

[srxqds]

Description

we are using Spanjson on ios use interp mode, it will throw exception when use expression generate deserialize/serialize code

Reproduction Steps

our source code:

internal class SpanJson
	{
		/// <summary>
		/// 一个简单的SpanJson测试用例
		/// </summary>
		[Test("SpanJson.SimpleSample")]
		public static void Run()
		{
			Person person = new Person { Name = "John Doe", Age = 30 };

			//Utf16
			{
				//Generic
				{
					var json = JsonSerializer.Generic.Utf16.Serialize(person);
					var deserializeData = JsonSerializer.Generic.Utf16.Deserialize<Person>(json);
					TestUtility.Check(deserializeData.Name == person.Name && deserializeData.Age == person.Age);
				}

				//NonGeneric
				{
					var json = JsonSerializer.NonGeneric.Utf16.Serialize(person);
					var deserializeData = JsonSerializer.NonGeneric.Utf16.Deserialize(json, typeof(Person)) as Person;
					TestUtility.Check(deserializeData.Name == person.Name && deserializeData.Age == person.Age);
				}
			}

			//Utf8
			{
				//Generic
				{
					var bytes = JsonSerializer.Generic.Utf8.Serialize(person);
					var deserializeData = JsonSerializer.Generic.Utf8.Deserialize<Person>(bytes);
					TestUtility.Check(deserializeData.Name == person.Name && deserializeData.Age == person.Age);
				}

				//NonGeneric
				{
					var bytes = JsonSerializer.NonGeneric.Utf8.Serialize(person);
					var deserializeData = JsonSerializer.NonGeneric.Utf8.Deserialize(bytes, typeof(Person)) as Person;
					TestUtility.Check(deserializeData.Name == person.Name && deserializeData.Age == person.Age);
				}
			}
		}
	}

	[JsonFormatterGenerator]
	public class Person
	{
		public string Name { get; set; }
		public int Age { get; set; }
	}

Expected behavior

walk correctly

Actual behavior

throw exception, the stacktrace show below:

@srxqds I'd expect the type of exception you're getting to occur under full aot mode. Can you double check that you are indeed using the interpreter?

@srxqds I'd expect the type of exception you're getting to occur under full aot mode. Can you double check that you are indeed using the interpreter?

yes, we use interpreter mode

[srxqds]

@steveisok @BrzVlad could you take time to fix it?

[BrzVlad]

What is Spanjson ? Boxing a byref type doesn't make sense to me.

What is Spanjson ? Boxing a byref type doesn't make sense to me.

the source code you can find here： https://github.com/Tornhoof/SpanJson/blob/3849bc28847e2e3ec6d2474283f512a3315b42ae/SpanJson/JsonSerializer.NonGeneric.cs#L213-L226

it can work on mono execute with jit and coreclr

[srxqds]

anyone can help to solve this problem?

[BrzVlad]

can you provide a full desktop console project that should fail with interpreter ?
