C# Get full name of data type

I am getting a datatype in code as "int32" however, what I actually need is the full name, "integer". Is this possible?

Here's the code for the data type:

public static List<Parameter> GetParameterMembers(Type parameterType)
        {
            var parameterList = new List<Parameter>();

            var returnTypeFields = parameterType.IsArray ? ((TypeInfo)parameterType.GetElementType()).DeclaredFields : ((TypeInfo)parameterType).DeclaredFields;

            returnTypeFields.ToList().ForEach(item =>
            {
                if (item.MemberType != MemberTypes.Field) return;

                parameterList.Add(new Parameter
                {
                    Name = item.Name,
                    Parameters = item.FieldType.IsClass && !IsNativeType(((FieldInfo)item).FieldType) ? GetParameterMembers(((FieldInfo)item).FieldType) : new List<Parameter>(),
                    DataType = item.FieldType.Name
                });
            });

            return parameterList;
        }
