AccessViolationException - 尝试打印
我正在尝试从 Reporting Services 打印报告，我采取的方法是：
渲染报告以获取 Byte[] 在客户端中创建一个文件（Something.pdf） 以读取模式将该文件加载到 FileStream 然后我尝试调用 http://support.microsoft.com 中描述的过程/kb/322091/en-us
如果您在方法 SendBytesToPrinter 中，有一行： bSuccess = WritePrinter(hPrinter, pBytes, dwCount, out dwWritten);
这一行给了我 AccessVilationException。
有谁知道如何解决这个问题，有没有更好的方法？
提前致谢
I am trying to print a report from Reporting Services, the approach I am taking is:
Render the report to get the Byte[]
Create a file in the client (Something.pdf)
Load that file in Read Mode to a FileStream
Then I try to make a call to the procedures described in http://support.microsoft.com/kb/322091/en-us
If you in method SendBytesToPrinter, there is a line:
bSuccess = WritePrinter(hPrinter, pBytes, dwCount, out dwWritten);
This line gives me the AccessVilationException.
Does anyone know how to solve this, and is there any better way of doing this?
Thanks in advance

您遇到内存分配/操作问题，可能是在为 pBytes 数组分配内存时。请参阅 http://social。 msdn.microsoft.com/forums/en-US/csharpgeneral/thread/cf744c83-fd7e-434c-b160-3f076d7491bf 用于该线程中解决的类似问题。
You have memory allocation/manipulation problems, problably when allocating memory for the pBytes array. See http://social.msdn.microsoft.com/forums/en-US/csharpgeneral/thread/cf744c83-fd7e-434c-b160-3f076d7491bf for a similar problem that is solved in that thread.
