IEnumerable的<字节>结果返回另一个方法 [英] IEnumerable<byte> result return to another method

问题描述

你好

我对IEnumerable有点失落。通常我会使用List< byte>但在我们的编程过程中，Resharper建议使用IEnumerable< byte>。但只想检查这是否正确实施？我们如何初始化它？

I'm a bit lost with the IEnumerable. Normally I would have use a List<byte> but during our programming Resharper suggesting making use of IEnumerable<byte>. But just want to check if this is correct implementation? And how do we initialize it?

  public IEnumerable<byte> BuildRecipeSendMessage(int DataIndex, DataTable RawRecipeData)
        {
            int recipeType = ModbusRecipeRawData.RecipeTypeID;
            IEnumerable<byte> messageArray = new List<byte>();

            switch (recipeType)
            {
                case 1:
                    var recipeTypeSite = new RecipeTypeSite();

                    recipeTypeSite.RecipeID = Convert.ToInt16(RawRecipeData.Rows[DataIndex][0]);
                    recipeTypeSite.IDDescription = RawRecipeData.Rows[DataIndex][1].ToString();

                    messageArray = _recipeMessageDefinition.BuildSiteMessageData(DataIndex, recipeTypeSite);
                    break;
                case 2:
                    var recipeTypePlant = new RecipeTypePlant();

                    recipeTypePlant.RecipeID = Convert.ToInt16(RawRecipeData.Rows[DataIndex][0]);
                    recipeTypePlant.IDDescription = RawRecipeData.Rows[DataIndex][1].ToString();

                    messageArray = _recipeMessageDefinition.BuildPlantMessageData(DataIndex, recipeTypePlant);
                    break;
                case 3:
                    var recipeTypeLocation = new RecipeTypeLocation();

                    recipeTypeLocation.RecipeID = Convert.ToInt16(RawRecipeData.Rows[DataIndex][0]);
                    recipeTypeLocation.IDDescription = RawRecipeData.Rows[DataIndex][1].ToString();

                    messageArray = _recipeMessageDefinition.BuildLocationMessageData(DataIndex, recipeTypeLocation);
                    break;
                case 4:
                    var recipeTypeProduct = new RecipeTypeProducts();

                    recipeTypeProduct.RecipeID = Convert.ToInt16(RawRecipeData.Rows[DataIndex][0]);
                    recipeTypeProduct.IDDescription = RawRecipeData.Rows[DataIndex][1].ToString();

                    messageArray = _recipeMessageDefinition.BuildProductMessageData(DataIndex, recipeTypeProduct);
                    break;
            }

            return messageArray;
        }

您好labjac，

Hi labjac,

>>但只想检查这是否正确实施？我们如何初始化它？

>> But just want to check if this is correct implementation? And how do we initialize it?

是的，这是一个正确的实现。

Yes, this is a correct implementation.

列表<>实现接口IEnumerable<>，所以你可以分配如下：

The List<> implements the interface IEnumerable<>, so you can assign as follows:

IEnumerable<byte> messageArray = new List<byte>();

顺便提一下，我注意到你还创建了以下线程：

a Class中的各种类或更多种方法

Various classes or rather various methods inside a Class

应用程序结构布局和类

将对象列表中的元素转换为特定数据类型

String Padleft但需要0x00而不是十六进制30

将字节添加到字节数组

如果这些线程中的问题已解决，请发布" ;标记为答案"如果他们面临类似的问题，它将帮助其他
