AutoMapper.dll 中发生“AutoMapper.AutoMapperMappingException”类型的异常，但未在用户代码中处理

使用 AutoMapper.dll 库时，可能会遇到一种名为 "AutoMapperMappingException" 的异常。这种异常通常是由于未在用户代码中对其进行处理而导致的。本文将探讨 AutoMapper.dll 异常的原因、解决方法，并提供一个案例代码来说明如何处理这种异常。

csharp
using AutoMapper;
public class SourceObject
{
    public int Number { get; set; }
    public string Text { get; set; }
}
public class DestinationObject
{
    public int Number { get; set; }
    public string Text { get; set; }
}
public class MappingProfile : Profile
{
    public MappingProfile()
    {
        CreateMap()
            .ForMember(dest => dest.Number, opt => opt.MapFrom(src => src.Number))
            .ForMember(dest => dest.Text, opt => opt.MapFrom(src => src.Text));
    }
}
public class Program
{
    public static void Main()
    {
        var source = new SourceObject { Number = 123, Text = "Hello" };
        var config = new MapperConfiguration(cfg => cfg.AddProfile());
        var mapper = new Mapper(config);
        try
        {
            var destination = mapper.Map(source);
            Console.WriteLine(destination.Number);
            Console.WriteLine(destination.Text);
        }
        catch (AutoMapperMappingException ex)
        {
            Console.WriteLine("映射失败：" + ex.Message);
        }
    }
}
