用于创建WCF类对象的代理

Question

请原谅我这个天真的问题。 我在客户端创建了一个WCF服务的服务引用，在示例中我提到他们已经创建了一个代理来创建WCF类的对象，我想了解＆＃34; ServiceCalculateCostClient＆＃34;来自。以下是客户电话 -

        CalculateCost.IServiceCalculateCost ICost = new CalculateCost.ServiceCalculateCostClient();
        CalculateCost.ProductData objProductData = new CalculateCost.ProductData();
        objProductData.ProductName = "Shirts";
        objProductData.ProductQuantity = 4;
        objProductData.PerProductCost = 200;
        Response.Write(ICost.getTotalCost(objProductData));

这是SVC代码

public class ServiceCalculateCost : IServiceCalculateCost
{
    string IServiceCalculateCost.getTotalCost(ProductData objProductData)
    {
        double totalCost = objProductData.PerProductCost * objProductData.ProductQuantity;
        return "The total cost for product " + objProductData.ProductName + " is " + totalCost.ToString();
    }
}
