Inside Dynamics Axapta源代码赏析(四)

第八章:Developing Applications Using Business Connector
这一章的代码主要演示如何通过Business Connector与Axapta交互
在Dynamics Axapta的客户端安装目录中找到Microsoft.Dynamics.BusinessConnectorNet.dll这个文件,添加到VS.NET的工程中.
1.HelloWorldBC.cs

class HelloWorldBC
    {
        static void Main(string[] args)
        {
            Axapta ax;

            // Log on to Dynamics AX
            ax = new Axapta();

            try
            {
                ax.Logon(null, null, null, null);
            }
            catch (Exception)
            {
                Console.WriteLine("Exception occurred during logon");
            }
            
            Console.WriteLine("Hello World!");
            
            // Log off from Dynamics AX
            ax.Logoff();

        }
    }

好久没用VS2005了,今天用了一下,智能提示忒爽了,Axapta编辑器也快点好起来吧......
搞不清楚四个参数都填null是怎么找到AOS的?本来想用Reflector反编译一下Microsoft.Dynamics.BusinessConnectorNet.dll,结果出来的是乱七八糟的东西,唉,忒不友好了......
2.AccessingDataBC.cs
遍历所有的料品,并打印料品Id和料品名称.

 // Instantiate a Dynamics AX record object for the 
            // record we want to work with
            AxaptaRecord axRecord = ax.CreateAxaptaRecord("InventTable");
            
            // Execute a query against the record 
            axRecord.ExecuteStmt("select * from %1");

            // Loop through the returned records
            // Extract the data from two fields for each record
            while (axRecord.Found)
            {
                invItemName = axRecord.get_Field(invItemNameField);
                invItemId = axRecord.get_Field(invItemIdField);

                Console.WriteLine(invItemId + "\t" + invItemName);

                // Go to the next record
                axRecord.Next();
            }

3.InvokingBusinessLogicBC.cs
调用Axapta中的静态方法.

 // Invoke the CallStaticClassMethod managed class
                // Provide the X++ class name and method to execute
                // The return value is placed into returnValue
                returnValue = ax.CallStaticClassMethod("InventoryManager",
                            "updateInventoryQty");

                // Use the return value to take some action
                if((Boolean)returnValue)
                    Console.WriteLine("Inventory quantity updated successfully");
                else
                    Console.WriteLine("Inventory quantity update failed");

其中的类InventoryManager在工程InsideDynamicsAXChapter8中定义.

这些连接和简单的操作倒还可以,不过Axapta的接口和SDK写得确实不甘恭维......
