【问题描述】：

我正在尝试使用来自第二个类的值和多维数组创建对象。我创造了什么：

class ProductData
    
        private ProductPrices[] prices;
        public string ParentName  get; set; 
        public string Name  get; set; 
        public string Description  get; set; 
        public string TechnicalDescription  get; set; 
        public bool Obsolete  get; set; 
        public bool Deleted  get; set; 
        public string Innercarton  get; set; 
        public string Outercarton  get; set; 
        public string Package  get; set; 
        public string Barcode  get; set; 
        public decimal Weight  get; set; 
        public decimal EndUserPrice  get; set; 
        public int MOQ  get; set; 
        public bool ComingSoon  get; set; 
        public bool NewProduct  get; set; 
        public string Equivalent  get; set; 
        public string ReplacedBy  get; set; 
        public ProductPrices[] Prices
        
            get
            
                return prices;
            
            set
            
                prices = value;
            
        
        public List<ProductFeatures> Feature  get; set; 
        public List<string> Specification  get; set; 
        public List<string> Image  get; set; 
        public string File  get; set; 
        public string Icon  get; set; 

    
    class ProductFeatures
    
        public string Feature;
    
    public class ProductPrices
    
        public decimal Price;
        public int MinQuantity;
        public DateTime validuntil;
        public string currency;
    

现在我想为 ProductPrices 设置一个多维数组。 所以，最后我会有这样的东西：

Dictionary<string, ProductData> productInfo = new Dictionary<string, ProductData>();
//Adding data to productInfo
string productName = productInfo.Name;
string description = productInfo.Description;
decimal wholesalePrice = productInfo.ProductPrices[0].Price;
int minQty = productInfo.ProductPrices[0].MinQuantity;

某处我错过了一些东西。我一直在寻找几个小时试图找到它，但不幸的是...... 提前致谢！

【问题讨论】：

std::vector<ProductPrices> Prices 是你想要的吗？

我在您的代码中没有看到需要二维气道的任何地方。看起来你只是不知道如何使用字典。你能解释一下你的问题吗？

【参考方案1】：

我已经找到了。 删除private ProductPrices[] prices; 并更改

public ProductPrices[] Prices
        
            get
            
                return prices;
            
            set
            
                prices = value;
            
         

到 public ProductPrices[] Prices get; set;

之后，你可以这样做：

ProductData prData = new ProductData();
prData.ParentName = "Parent name";
prData.Name = "Some name";
prData.Prices = new ProductPrices[enterArrayCount];
ProductPrices prdPrices = new ProductPrices();
prdPrices.Price = Convert.ToDecimal(yourDecimalValue);
prdPrices.MinQuantity = 8;
prdPrices.Currency = "Eur";
prData.Prices[firstIndex] = prdPrices; //So firstIndex must increase after a value has been set.
