AX export the 'CSV' file by three ways

Way 1: Use 'TextBuffer' to Export CSV from AX.

 1 static void ExportToCSVFile01(Args _args)  
 2 {  
 3     TextBuffer              textBuffer  = new TextBuffer();  
 4     InventTable             inventTable;  
 5     FileIoPermission        perm;  
 6     counter                 Lines;  
 7        
 8     #define.ExampleFile(@"c:\\AX2009.csv")  
 9     #define.ExampleOpenMode("W")  
10 　　;  
11     try 
12     {  
13         perm = new FileIoPermission(#ExampleFile, #ExampleOpenMode);  
14         perm.assert();  
15    
16            
17         textBuffer.appendText("Item Id,");//必须用逗号分开
18         textBuffer.appendText("Item Name,");//必须用逗号分开
19         textBuffer.appendText("Item Type");  
20         textBuffer.appendText("\n");//下一行必须以回车分开 
21    
22         while select InventTable  
23             where  inventTable.ItemType == ItemType::BOM  
24             &&     inventTable.ItemId like "20*" 
25         {  
26             textBuffer.appendText(strfmt("%1,",inventTable.ItemId));  
27               
28             textBuffer.appendText(strfmt("%1,",global::strReplace(inventTable.ItemName,",","")));
29               
30             textBuffer.appendText(enum2str(inventTable.ItemType));  
31             textBuffer.appendText("\n");  
32         }  
33         Lines = textBuffer.numLines();  
34        
35         try 
36         {  
37             if (textBuffer.toFile(#ExampleFile))  
38                 info( strfmt("File Generated as %1.total insert %2 Lines",#ExampleFile,Lines));  
39         }  
40         catch ( Exception::Error )  
41         {  
42             error ("Generated file error.");  
43         }  
44         CodeAccessPermission::revertAssert();  
45     }  
46     catch (Exception::Deadlock)  
47     {  
48         retry;  
49     }  
50 }

Way 2: Use dialog to get the saving path and save the file.

static void ExportToCSVFile03(Args _args)  
{  
    TextBuffer          textBuffer = new TextBuffer();  
    CustTable           CustTable;  
    FileNameFilter      Filter = ["CSV file", "*.csv"];  
    FileName            FileName;  
    #WinAPI  
　　;  
    FileName = winapi::getSaveFileName(infolog.hWnd(), filter, @"c:\\desktop", "Save as CSV file","csv","Customer Infomation");  
    if(!FileName)  
        return ;  
           
    textBuffer.appendText("Customer,");  
    textBuffer.appendText("Group,");  
    textBuffer.appendText("Currency,");  
    textBuffer.appendText("RecId\n");  
       
    while select CustTable  
    {  
        textBuffer.appendText(strfmt("%1,", CustTable.AccountNum));  
        textBuffer.appendText(strfmt("%1,", CustTable.CustGroup));  
        textBuffer.appendText(strfmt("%1,", CustTable.Currency));  
        textBuffer.appendText(strfmt("%1",  CustTable.RecId));  
           
        textBuffer.appendText("\n");//next row  
    }  
   
    if (textBuffer.toFile(FileName))  
    {  
        info( strfmt("File Generated as %1.Total %2 Lines",FileName,textBuffer.numLines()));  
        winapi::shellExecute(FileName);  
    }  
}

Way 3: Use the system class 'SysExcelApplication' to export CSV file, lowest performance.

 1 static void ExportToCSVFile02(Args _args)  
 2 {  
 3     SysExcelApplication     application;  
 4     SysExcelWorkBooks       workBooks;  
 5     SysExcelWorkBook        workBook;  
 6     SysExcelWorkSheet       workSheet;  
 7     SysExcelCells           cell;  
 8     str                     filename = @"c:\\test";  
 9    
10     ;  
11     application = SysExcelApplication::construct();  
12     workBooks   = application.workbooks();  
13     workBook    = workBooks.add();  
14     workSheet   = workBook.worksheets().itemFromNum(1);  
15     cell = worksheet.cells();  
16     cell.item(1,1).value("itemid");  
17     cell.item(1,2).value("ItemName");  
18    
19     workbook.saveAs(filename,6);//6 just CSV excel file format  
20     application.quit();  
21    
22 }
