我有一个用于加密和解密的dotnet脚本。我必须在installshield中传递setvalues函数的参数。我怎样才能做到这一点？ Dotnet代码如下。我有汇编（.dll）文件。

这是我在完成下面的屏幕截图中提到的所有内容并做一些R＆amp; D后收到的错误。当调用加密custiom操作但是它引发异常时，提到了“C：\ Program Files（x86）\\。config”这个目录。

Answer 1

是的，可以通过以下步骤完成： 1-在c＃installer类中编写所需的功能（确保您使用的是安装程序类）

2-编译并将你的dll添加到installshield中（推荐为这个dll创建一个单独的组件） 3-选择组件视图 - ＆gt;选择上面的组件并转到.Net设置部分，将“.Net Installer class”设置为true。设置“.net安装程序类参数”

参数作为键/值对传递，例如

/targetDirectory="[INSTALLDIR]\"

所有步骤都相同，只是添加了截图。

使用安装程序类和加密/解密类创建一个dll。
将dll和配置文件添加到组件（如上所述），如果配置文件已经添加到其他组件，那么就可以了。无需再添加。
我添加并检索了INSTALLDIR变量作为预定义的参数。如果你想从用户（从一些自定义文本框）接收一些输入，那么你需要定义自己的变量来存储和传递值作为参数。
使用安装程序类创建dll，并为其他任务
创建组件并添加文件
将dll标记为安装程序类并传递参数

这是安装程序类：

using System;
using System.Text;
using System.IO;
using System.Diagnostics;
using System.ComponentModel;
using System.Configuration.Install;
using System.Collections.Generic;


namespace EncryptionDecryption
{
    [RunInstaller(true)]
    public class InstallerClassDemo : Installer
    {
        private string installationDirectory=string.Empty;
        private string testString=string.Empty ;

        public override void Install(System.Collections.IDictionary stateSaver)
        {
            base.Install(stateSaver);

            try
            {
                //For testing purpose only.. work only in debug mode when pdb files are deployed as well.
                //Debugger.Break();

                installationDirectory = Context.Parameters["INSTALLDIR"];

                //I believe, the config file must be located in the installation directory if so, then use the following way to compute path

                string configFilePath = Path.Combine(installationDirectory, "myConfigFile.config");
                EncrptionHelper.SetValue(configFilePath, "testKey", "testValue");
            }
            catch (Exception ex)
            {
                System.Diagnostics.Debug.WriteLine(ex.Message);
            }

        }

        protected override void OnCommitted(System.Collections.IDictionary savedState)
        {
            base.OnCommitted(savedState);
        }

        public override void Uninstall(System.Collections.IDictionary savedState)
        {
            base.Uninstall(savedState);
        }


    }
}

Answer 2

我认为installshield不能（或需要额外的工作）来读取程序集，但是你可以运行简单的控制台应用程序，它使用installscript中的程序集并从installshield传递参数。

创建简单的控制台应用程序

在支持文件中包含控制台应用程序

复制到安装文件夹或程序集位置，以便控制台应用程序可以访问程序集

使用launchappandwait

从installscript启动

如果consoleapp.exe不再使用，只需将其删除即可。

如何在installshield中传递托管代码dll的参数？
