在csharp中创建一个ram驱动器 [英] creating a ram drive in csharp
问题描述
目前我在c＃中实现了ghostscript应用程序。
我可以通过dllimport导入的Dll函数全部写入磁盘
。
因为我想要base64编码文件，我不想慢速访问磁盘，
但是要在内存中执行所有功能。
有人能告诉我是否有办法可以创建一个ram
驱动器，我可以写信给它？
At我正在把我的屁股甩掉但却找不到任何东西的那一刻
TIA
Otto
At the moment i am implementing a ghostscript application in c#.
The Dll functions that i can import via dllimport all write to disk
directly.
As i want base64 encode the files, i don''t want the slow disk access,
but do all functions in memory.
Could someone tell me if there is a way in which i can create a ram
drive, which i can write to ??
At the moment i am gooling my butt off but can''t find anything
TIA

如何使用内存映射文件？

How about using memory-mapped files instead?

你好ebbe
我从gsdll32.dll使用以下dll导入
[DllImport（" gsdll32.dll"，EntryPoint） =" gsapi_init_with_args"）]
private static extern int gsapi_init_with_args（IntPtr instance，int
argc，IntPtr argv）;
如您所见，dll使用argcounter和argvalues。值为
，其中包含以下值：
args [0] =" -dNOPAUSE";
args [ 1] =" -dBATCH";
args [2] =" -dSAFER";
args [3] =" -sDEVICE = pdfwrite" ;;
args [4] =" -sOutputFile =" + outputFile;
args [5] = inputFile;
both inputfile和outputfile包含路径或unc。使用任何流类型都没有
功能。
可以通过路径到达内存映射文件。
或内存映射文件只是一种指针我必须通过
从一个应用程序到另一个应用程序???

Hello ebbe
I use the following dll import from gsdll32.dll
[DllImport("gsdll32.dll", EntryPoint="gsapi_init_with_args")]
private static extern int gsapi_init_with_args (IntPtr instance, int
argc, IntPtr argv);
As you can see the dll uses a argcounter and argvalues. The values are
filled with the following values:
args[0]="-dNOPAUSE";
args[1]="-dBATCH";
args[2]="-dSAFER";
args[3]="-sDEVICE=pdfwrite";
args[4]="-sOutputFile="+outputFile;
args[5]=inputFile;
both inputfile and outputfile contain a path or unc. there is no
functionality for using any stream type''s.
can the memory mapped files be reached by a path.
or are memory mapped files just kind of pointer that i have to pass
from one application to another ???

DLL函数是写入文件还是写入文件流？如果是一个
文件流，那么你可以通过使用
内存流获得你想要的效果。
DLL - memoryStream -Base64 -disk
rossum
Do the DLL functions write to a file, or to a file stream? If to a
file stream then you might get the effect that you want by using a
memory stream.
DLL -memoryStream -Base64 -disk
