我在 SSIS 包中有一个脚本任务，像这样，

public ReadListItemsSPOnline(string siteUrl, string email, string password, int requestTimeout)
        {
            _clientContext = new ClientContext(siteUrl);
            var securePassword = new SecureString();
            foreach (char c in password) securePassword.AppendChar(c);

            String[] BypssArr = { "XXXXXX$" };
            myProxy = new System.Net.WebProxy();
            **myProxy.Address = new Uri("http://abc-proxy-in.abc.net:2020");**
            myProxy.UseDefaultCredentials = true;
            myProxy.BypassList = BypssArr;
            System.Net.WebRequest.DefaultWebProxy = myProxy;
            _clientContext.ExecutingWebRequest += (s, e) =>

            {

                //e.WebRequestExecutor.WebRequest.Headers.Add("X-FORMS_BASED_AUTH_ACCEPTED", "f");

                e.WebRequestExecutor.WebRequest.Proxy.Credentials = System.Net.CredentialCache.DefaultCredentials;

            };

            _clientContext.Credentials = new SharePointOnlineCredentials(email, securePassword);
            _clientContext.RequestTimeout = requestTimeout;
            _clientContext.Load(_clientContext.Web);
            _clientContext.ExecuteQuery();
        }

如您所见，代理服务器是硬编码的http://abc-proxy-in.abc.net:2020。我想让代理地址可配置。我在我的包中添加了一个包参数（$project::Proxy_Name）我想在脚本任务中使用这个参数来使其更具可配置性。您能否让我知道我应该在此代码中进行哪些更改以使其更具可配置性，因为我不是 .net 人。

关于如何使用它们的脚本任务就在那里：

#region Help:  Using Integration Services variables and parameters in a script
    /* To use a variable in this script, first ensure that the variable has been added to 
     * either the list contained in the ReadOnlyVariables property or the list contained in 
     * the ReadWriteVariables property of this script task, according to whether or not your
     * code needs to write to the variable.  To add the variable, save this script, close this instance of
     * Visual Studio, and update the ReadOnlyVariables and 
     * ReadWriteVariables properties in the Script Transformation Editor window.
     * To use a parameter in this script, follow the same steps. Parameters are always read-only.
     * 
     * Example of reading from a variable:
     *  DateTime startTime = (DateTime) Dts.Variables["System::StartTime"].Value;
     * 
     * Example of writing to a variable:
     *  Dts.Variables["User::myStringVariable"].Value = "new value";
     * 
     * Example of reading from a package parameter:
     *  int batchId = (int) Dts.Variables["$Package::batchId"].Value;
     *  
     * Example of reading from a project parameter:
     *  int batchId = (int) Dts.Variables["$Project::batchId"].Value;
     * 
     * Example of reading from a sensitive project parameter:
     *  int batchId = (int) Dts.Variables["$Project::batchId"].GetSensitiveValue();
     * */
