c# - 格式化文件中的文本表，将每行两行合并为一行

Question

我正在尝试将一些信息写入文本文件，但第二行在两行之间留有空格

代码:

private void CreateDriversList()
{
    StreamWriter w = new StreamWriter(contentDirectory + "\\" + "Drivers.txt");
    w.WriteLine("Module Name  Display Name           Driver Type   Link Date");
    w.WriteLine("============ ====================== ============= ======================");
    //Declare, Search, and Get the Properties in Win32_SystemDriver
    System.Management.SelectQuery query = new System.Management.SelectQuery("Win32_SystemDriver");
    System.Management.ManagementObjectSearcher searcher = new System.Management.ManagementObjectSearcher(query);
    foreach (System.Management.ManagementObject ManageObject in searcher.Get())
    {
        w.WriteLine(ManageObject["Name"].ToString());
        w.WriteLine("             " + ManageObject["DisplayName"].ToString());
    }
    w.Close();
}

一旦我添加了行:

w.WriteLine("             " + ManageObject["DisplayName"].ToString());

文本文件中的结果是这样的:

Module Name  Display Name           Driver Type   Link Date
============ ====================== ============= ======================
1394ohci
             1394 OHCI Compliant Host Controller
3ware
             3ware
ACPI
             Microsoft ACPI Driver
acpiex
             Microsoft ACPIEx Driver
acpipagr

在我添加该行之前，文本文件是这样的:

Module Name  Display Name           Driver Type   Link Date
============ ====================== ============= ======================
1394ohci
3ware
ACPI
acpiex
acpipagr
AcpiPmi

我现在只想添加显示名称行，所以我添加了空格，这样该行将从显示名称下开始，然后在两行之间添加空格。

我该如何解决？

最后的文本文件应该是这样的:

Module Name  Display Name           Driver Type   Link Date             
============ ====================== ============= ======================
1394ohci     1394 OHCI Compliant Ho Kernel        7/26/2012 5:26:46 AM  
3ware        3ware                  Kernel        3/8/2012 10:33:45 PM  
ACPI         Microsoft ACPI Driver  Kernel        9/20/2012 9:09:16 AM  
acpiex       Microsoft ACPIEx Drive Kernel        7/26/2012 5:25:57 AM  
acpipagr     ACPI Processor Aggrega Kernel        7/26/2012 5:27:16 AM  
AcpiPmi      ACPI Power Meter Drive Kernel        7/26/2012 5:27:33 AM  
acpitime     ACPI Wake Alarm Driver Kernel        7/26/2012 5:27:37 AM  

并且在显示名称行中，也可能在模块名称行中，以确保名称将在一行中显示全名。

例如显示名称:1394 OHCI Compliant Ho应该是:1394 OHCI 兼容主机 Controller

============ ====================== ============= ======================
1394ohci     1394 OHCI Compliant Host Controller
3ware        3ware
ACPI         Microsoft ACPI Driver
acpiex       Microsoft ACPIEx Driver
acpipagr     ACPI Processor Aggregator Driver
AcpiPmi      ACPI Power Meter Driver

您在循环中调用了两次 WriteLine - 因此它为每个项目添加了两行。您只想添加一个行，例如

w.WriteLine("{0} {1}", ManageObject["Name"], ManageObject["DisplayName"]);

虽然这不会填充空格，因此您需要在 composite format string 中包含对齐方面.你想要左填充，所以你需要负对齐，看起来你想要空格前的 12 个字符，所以:

w.WriteLine("{0,-12} {1}", ManageObject["Name"], ManageObject["DisplayName"]);
