Question

我是C＃环境中使用PowerShell的新手。我已经创建了一个多行文本框来键入powershell脚本来执行它，它工作正常。现在我想摆脱文本框中的输入并且有3个选定的变量（Container和NumIP）而不是传递给powerscript脚本文件然后执行它。如何获取这些文件并将这些变量传递给C＃中的powershell脚本文件？或者我是否必须在C＃中创建脚本字符串？

这是一个有效的PowerShell脚本文件，因为它有很长的代码，我要把1行代码放在我要将这2个变量传递给这2个参数的地方。

    [string]$ContainerIn=$args[0]
[int]$ips2get=$args[1]

这里是C＃代码，

protected void ExecuteCode_Click(object sender, EventArgs e)
    {
        // Clean the Result TextBox
        ResultBox.Text = string.Empty;
        ResultBox.ForeColor = System.Drawing.ColorTranslator.FromHtml("#FFFFFF");

        string str = "";

        //These 3 input varaibles will pass to powershell script to get specific results
        string env = "";
        string container = "";
        string numIPs = "";

        //assign dropdown selected value to variable to pass to script
        container = DropDownListContainer.SelectedValue;
        numIPs = DropDownListIP.SelectedValue;

        if (container == "H02" || container == "H07" || container == "H08")
        {
            env = "Prod";
        }
        else
        {
            env = "NonProd";
        }

        // Create a Powershell
        Runspace runSpace = RunspaceFactory.CreateRunspace();
        runSpace.Open();
        Pipeline pipeline = runSpace.CreatePipeline();

        Command invokeScript = new Command("Invoke-Command");
        RunspaceInvoke invoke = new RunspaceInvoke();

        //Add powershell command/script functions into scriptblock
        ScriptBlock sb = invoke.Invoke(@"{D:\Scripts\Get-FreeAddress.ps1}")[0].BaseObject as ScriptBlock;
        invokeScript.Parameters.Add("scriptBlock", sb);
        invokeScript.Parameters.Add("computername", TextBoxServer.Text);

        pipeline.Commands.Add(invokeScript);
        Collection<PSObject> output = pipeline.Invoke();

        //splitting results in new lines
        foreach (PSObject psObject in output)
        {

            str = str + psObject + "\r\n";
            //str = psObject + "\r\n";
            //str += "\n" + psObject;
            //str = str + Environment.NewLine + psObject;

        }

        if (str == "")
        {
            str = "Error";

            ResultBox.ForeColor = System.Drawing.ColorTranslator.FromHtml("#FF0000");
        }

        //print out powershell output result
        ResultBox.Text = str;

    }

我知道我可能需要更改此代码ScriptBlock sb = invoke.Invoke("{" + PowerShellCodeBox.Text + "}")[0].BaseObject as ScriptBlock;

一种方法是修改脚本块创建，如下所示：

string sbstr = String.Format("{D:\Scripts\Get-FreeAddress.ps1 -Env:"{0}" -Container:"{1}" -NumIPs:{2} -GiveInfo:$false}", envTB.Text, contTB.Text, numipTB.Text);
ScriptBlock sb = invoke.Invoke(sbstr)[0].BaseObject as ScriptBlock;

为了将本地脚本文件传播到远程计算机以运行，您需要这样做：

Command invokeScript = new Command("Invoke-Command");
invokeScript.Parameters.Add("computername", TextBoxServer.Text);
invokeScript.Parameters.Add("filepath", "D:\Scripts\Get-FreeAddress.ps1");
invokeScript.Parameters.Add("argumentlist", new[]{envTB.Text, contTB.Text, numipTB.Text, False});

Answer 2

我终于完成了这项工作，

我只需要修改为ScriptBlock sb = invoke.Invoke(@"{D:\Scripts\Get-FreeAddress.ps1 '"+container+"' "+numIPs+"}")[0].BaseObject as ScriptBlock;

powershell脚本参数将获取容器和numIPs变量。

C＃，如何获取powershell脚本文件并将一些变量传递给脚本？
