Axapta:从容器字段加载文件和将文件保存到容器字段 [英] Axapta: Load and Save file from and to container field

问题描述

我需要自定义AX以加载具有任意大小的任意文件，并将其作为容器字段保存到数据库.我还需要从该容器字段中读回并将内容写入文件，该文件应包含与加载之前完全相同的文件内容.

I need to customize AX to load an arbitrary file with arbitrary size and save it to database as a container field. I also need to read back from that container field and write the content into a file, which should contain exactly the same file content as before load.

我曾经在BinaryIO上尝试过，不幸的是没有运气

I had tried with BinaryIO, unfortunately with no luck

static void BinDataTest(Args _args)
{
    BinData b = new BinData();
    Container c;
    b.loadFile(@"C:\Windows\notepad.exe");
    info(int2str(b.size()));
    c = b.getData();
    b = new BinData();
    b.setData(c);
    info(int2str(b.size()));
    b.saveFile(@"C:\Temp\notepad.exe");
}
