如何调用ac＃函数将值填入razor html文本框？

Question

I am using the function that fetches the output from PowerShell script into the output String variable. I need to call that function inside an @HTMLTextBox to load the value.

I have created the function and using razor format to invoke the function inside the textbox element.

@using System.Management.Automation
@functions {

public string PowerShellExecutor(string script) {
    var shell = PowerShell.Create();
    string outString = "";
    shell.Commands.AddScript(script);
    var results = shell.Invoke();
    if (results.Count>0)
    {
        var builder = new StringBuilder();
        foreach (var psObj in results)
        {
            builder.Append(psObj.BaseObject.ToString() + "\r\n");

        }
        outString = Server.HtmlEncode(builder.ToString());
    }
    return outString;
  }
}

<div class="col-md-12">
                @Html.TextBox("txtDirectory", @PowerShellExecutor("$env:USERDNSDOMAIN") , new { @class = "form-control", @type = "number"})
</div>

The textbox is suppose to fill the value of the output obtained when the command is passed through the function. However, It shows blank.

删除PowerShellExecutor的@，您还应删除@type = "number"以使文本框接受字符串。

@Html.TextBox("txtDirectory", PowerShellExecutor("$env:USERDNSDOMAIN") , new { @class = "form-control"})
