将 string[] 数组字段分配给另一个相同类型的数组字段 c#

Question

我的解决方案中定义了两个类

public class Registration {
    [...]
    public list<Account> Accounts {get; set;}
}

public class Account {
    [...]       
    public string Code { get; set; }
    public string Name { get; set; }
    public string Address { get; set; }
}

在我正在使用的 Web 服务中，可以使用以下类定义

public partial class VendReg {
    [...]
    private Payment_Details[] requestDetailsField;
    
    [System.Xml.Serialization.XmlArrayItemAttribute(IsNullable=false)]
    public Payment_Details[] RequestDetails {
        get {
            return this.requestDetailsField;
        }
        set {
            this.requestDetailsField = value;
        }
    }       
}


public partial class Payment_Details {
          
    private string bk_CodeField;
    
    private string bk_NameField;
    
    private string bk_AddressField;
                         
    public string Bk_Code {
        get {
            return this.bk_CodeField;
        }
        set {
            this.bk_CodeField = value;
        }
    }
    
    public string Bk_Name {
        get {
            return this.bk_NameField;
        }
        set {
            this.bk_NameField = value;
        }
    }
    
    public string Bk_Address {
        get {
            return this.bk_AddressField;
        }
        set {
            this.bk_AddressField = value;
        }
    }         
}

我想将Account 分配给Request Details，这是一个Payment_Details 数组。我在下面尝试了这段代码 vendReg.RequestDetails = registration.Accounts.Cast<Payment_Details>().ToArray();

我得到了无效的转换异常：无法将类型为“Account”的对象转换为类型“Payment_Details”

请指导我做错了什么

您需要自己转换它（或者您可以查看 Automapper 之类的东西）

vendReg.RequestDetails = registration.Accounts.Select(acc => 
   new Payment_Details {
      Bk_Code = acc.Code,
      Bk_Name = acc.Name,
      Bk_Address = acc.Address
   }).ToArray();
