如何将IDL文件中的函数转换为C＃ [英] how to convert the function in IDL file to C#

问题描述

我的idl文件中有[in，out，size_is（Size）] byte compress_page [*]参数。现在我们正在迁移到wcf。

你能不能告诉我我们如何转换成C＃。

for ex：



在IDL文件中查看此函数

hi ,

i am having [in,out,size_is(Size)] byte compress_page[*] parameter in my idl file. now we are migrating to wcf.
can you please tell me know how we convert into C#.
for ex:

see this function in IDL file

long RMTReadMultiPages(  [in] File fh,
                      [in, string] char prj[],
                      [in] long fileno,
                      [in] long extno,
                      [in] long pageStart,
                      [in,out] long *numPages,
                      [in] long transferSize,
                      [out] short *failCode,
                      [in,out,size_is(Size)] byte compress_page[*]
                     );

i必须用C＃编写这个函数。

i have to write this function in C#.

I am trying to host my Wcf service with Entlib 5.0 Validation. When servie operation contracts go for validation they get crash. Whiel investigating, I found that ref keyword in Wcf service's operation giving this problem. E.g.:

Operation contract in service is like:

public void GetData(int ID, string name, ref string location) {};

Now, while validating string location, it gets crash and if I remove ref keyword it works fine.

Though, in EntLib version 4.0 there are no such issues.
i tried replacing "ref" with "out" the issue was solved..
that ref replacing with out means [in, out] replaced with out.. i am getting some junk values in "compress_page", i am suspecting that this because of When it acts as an input it taking junk values.

谢谢f

此列表可能会给您一些帮助。

平台调用数据类型 [ ^ ]



[in]可以删除

[out]对应 out

[in，out]可以是替换为 ref





以下是对IDL的概述了解接口定义语言 [ ^ ]



Marshal Class [ ^ ]也可能有所帮助。



这是一个关于PInvoke的Wiki页面。 http://en.wikipedia.org/wiki/Platform_Invocation_Services [ ^ ]

PInvoke。 net [ ^ ]可以作为参考使用。 （但是，我现在无法访问该网站）



也许StackOverflow上的这个问题会给出一些线索：将接口IDL文件转换为C＃ [ ^ ]



或者这篇CP文章： Essential P / Invoke [ ^ ]

This list might give you some help.
Platform Invoke Data Types[^]

[in] can be removed
[out] corresponds to out
[in,out] can be replaced by ref


Here is an overview over IDL Understanding Interface Definition Language[^]

The Marshal Class[^] might be of help too.

Here is a Wiki page about PInvoke. http://en.wikipedia.org/wiki/Platform_Invocation_Services[^]
PInvoke.net[^] can be good to use as a reference. (However, I cannot access the site at the moment)

Maybe this question at StackOverflow will give some clues: Convert Interface IDL file to C#[^]
