当使用Automapper进行映射操作时,有可能会遇到构造异常,主要的表现形式是程序报告未能创建映射,这通常发生在目标对象无法被正确地创建或转换的情况下。以下是一些可能的解决方案:
public class ProductDto { public int Id { get; set; } public string Name { get; set; } public decimal Price { get; set; } }
public class Product { public Product(int id, string name, decimal price) { Id = id; Name = name; Price = price; }
public int Id { get; set; }
public string Name { get; set; }
public decimal Price { get; set; }
public Product()
{
// 默认构造函数
}
}
Mapper.Initialize(cfg =>
{
cfg.CreateMap
// 映射代码
var product = new Product(1, "Apple", 2.99m);
var dto = Mapper.Map
public class InvariantDecimalToStringConverter : ITypeConverter
public class ProductProfile : Profile
{
public ProductProfile()
{
CreateMap
Mapper.Initialize(cfg =>
{
cfg.AddProfile
// 映射代码 var product = new Product(1, "Apple", 2.
