无法引用dll [英] Can't reference dll
问题描述
尝试从Realia
COBOL程序（32位）添加对DLL程序的引用时出错。错误消息显示请确保
文件可访问，并且它是有效的程序集或COM组件。我可以使用C ++而不是C＃来
访问此文件。我的COBOL DLL程序通过
引用传递数据。我的编码如下所示：
[DllImport（" progcmp1.dll"，CharSet = CharSet.Auto，EntryPoint =" TRANPROG"，
CallingConvention = CallingConvention.StdCall）]
public static extern void TRANPROG（string parms）;
private void OnSubmit（object sender，EventArgs e）
{
StringBuilder parms = new StringBuilder（" 00000000"，87）;
TRANPROG（parms.ToString（））;
}
I get an error when trying to add a reference to a DLL program from a Realia
COBOL program that is 32 bit. The error message says "Please make sure the
file is accessible and that it is a valid assembly or COM component. I can
access this file using C++ but not C#. My COBOL DLL program passes data by
reference. My coding is shown below:
[DllImport("progcmp1.dll", CharSet=CharSet.Auto, EntryPoint="TRANPROG",
CallingConvention=CallingConvention.StdCall)]
public static extern void TRANPROG(string parms);
private void OnSubmit(object sender, EventArgs e)
{
StringBuilder parms = new StringBuilder("00000000", 87);
TRANPROG(parms.ToString());
}
推荐答案
只是一个想法：
你可能想尝试发送你的信息作为一个参考。
[DllImport（" progcmp1.dll"，CharSet = CharSet.Auto，EntryPoint =" TRANPROG"，
CallingConvention = CallingConvention。 StdCall）]
public static extern void TRANPROG（ref string parms）;
private void OnSubmit（object sender，EventArgs e）
{
StringBuilder parms = new StringBuilder（" 00000000" ;，87）;
string strParams = params.ToString（）;
TRANPROG（ref strParms）;
}
" Parrot"写道：
Just a thought:
You might want to try sending your info as a reference also.
[DllImport("progcmp1.dll", CharSet=CharSet.Auto, EntryPoint="TRANPROG",
CallingConvention=CallingConvention.StdCall)]
public static extern void TRANPROG(ref string parms);
private void OnSubmit(object sender, EventArgs e)
{
StringBuilder parms = new StringBuilder("00000000", 87);
string strParams = params.ToString();
TRANPROG(ref strParms);
}

你不能在你的项目中添加对DLL的引用，除非它是一个程序集
或一个COM库。如果你想访问一个既不是DLL，只需将它复制到一个可访问的地方（你的应用程序的\bin目录，
例子）。不要将其作为参考添加。

You can''t add a reference to a DLL to your project unless it''s an assembly
or a COM library. If you want to access a DLL that''s neither, simply copy it
to an accessible place (the \bin directory of your application, for
example). Do not add it as a reference.

先生。 Mostert：
我很好奇：如果你没有为你的项目添加一个DLL并将其包含在
\ bin文件夹中......你怎么称呼它？
我没有这方面的经验，但最近有人在工作，问我
如何做一些非常相似的事情。

Mr. Mostert:
I''m curious: If you don''t add a DLL to your project and include it in the
\bin folder instead... how do you call it?
I have no experience in this, but someone at work recently came asking me
how to do something very similar.
