Question

我需要这些可变名称是动态的。为了举例说明我正在看的内容＆gt; https://ebaydts.com/eBayKBDetails?KBid=1742

现在在上面的链接中，它有一些变量代码。

    //Specify Variations
    VariationTypeCollection VarCol = new VariationTypeCollection();

    //Variation 1 - Black S
    VariationType var1 = new VariationType();
    var1.SKU = "VAR1";
    var1.Quantity = 10;
    var1.StartPrice = new AmountType();
    var1.StartPrice.currencyID = CurrencyCodeType.AUD;
    var1.StartPrice.Value = 35;
    var1.VariationSpecifics = new NameValueListTypeCollection();

    NameValueListType Var1Spec1   = new NameValueListType();
    StringCollection Var1Spec1Valuecoll  = new StringCollection();

    Var1Spec1.Name = "Colour";
    Var1Spec1Valuecoll.Add("Black");
    Var1Spec1.Value = Var1Spec1Valuecoll;

    var1.VariationSpecifics.Add(Var1Spec1);

    NameValueListType Var1Spec2 = new NameValueListType();
    StringCollection Var1Spec2Valuecoll = new StringCollection();

    Var1Spec2.Name = "Size";
    Var1Spec2Valuecoll.Add("S");
    Var1Spec2.Value = Var1Spec2Valuecoll;

    var1.VariationSpecifics.Add(Var1Spec2);

    VarCol.Add(var1);

    //Variation 2 - Black L
    VariationType var2 = new VariationType();
    var2.SKU = "VAR2";
    var2.Quantity = 10;
    var2.StartPrice = new AmountType();
    var2.StartPrice.currencyID = CurrencyCodeType.AUD;
    var2.StartPrice.Value = 45;

    var2.VariationSpecifics = new NameValueListTypeCollection();

    NameValueListType Var2Spec1 = new NameValueListType();
    StringCollection Var2Spec1Valuecoll = new StringCollection();

    Var2Spec1.Name = "Colour";
    Var2Spec1Valuecoll.Add("Black");
    Var2Spec1.Value = Var2Spec1Valuecoll;

    var2.VariationSpecifics.Add(Var2Spec1);

    NameValueListType Var2Spec2 = new NameValueListType();
    StringCollection Var2Spec2Valuecoll = new StringCollection();

    Var2Spec2.Name = "Size";
    Var2Spec2Valuecoll.Add("L");
    Var2Spec2.Value = Var2Spec2Valuecoll;

    var2.VariationSpecifics.Add(Var2Spec2);

    VarCol.Add(var2);

所以我正在使用的代码我想动态创建可变名称，因为你可以想象我无法知道每个产品有多少变化。

当然，我可以计算变化量，并设置一个if else结构

if (count == 1) {
     //some code
}
else if (count == 2) {
     //some code
}

但这似乎不是一个好的解决方案。

此时需要在每个循环内输出变量

以下是我正在使用的代码：

string UPC = "";
                string Brand = "";
                string MPN = "";

                if (!String.IsNullOrEmpty(product.Gtin))
                    UPC = product.Gtin;

                if (!String.IsNullOrEmpty(ebayProduct.EbayProductBrandName))
                    Brand = ebayProduct.EbayProductBrandName;

                if (!String.IsNullOrEmpty(product.ManufacturerPartNumber))
                    MPN = product.ManufacturerPartNumber;

                //create the call object
                AddFixedPriceItemCall AddFPItemCall = new AddFixedPriceItemCall(context);

                AddFPItemCall.AutoSetItemUUID = true;

                //create an item object and set the properties
                ItemType item = new ItemType();

                //set the item condition depending on the value from GetCategoryFeatures
                item.ConditionID = 1000; //new

任何人都知道我在这里可以做些什么。干杯

Answer 1

最接近＆＃34;动态变量名称＆＃34;是一本字典。

Dictionary<string, string> variables = new Dictionary<string, string>();
variables.Add("var1", "test1");
variables.Add("var2", "test2");
MessageBox.Show(variables["var1"]); // will display test1

如果每个＆＃34;变量＆＃34;都有一组所需数据，请创建一个类或结构（也许称之为＆＃34; TheData＆＃34;）

Dictionary<string, TheData> variables = new Dictionary<string, TheData>();
variables.Add("var1", new TheData() { price = 25.28, upc = "01121...", manufacturer = "ACME" });
