我使用For / f循环来读取存储在文件中的值（内容位于我原始帖子的底部）并将参数存储到使用count + 1动态生成的变量，这样可以使用的参数数量是开放式的（因为预期用途是将共享安装到驱动器盘符，可能有任意数量的驱动器，因此可能有参数）。
所使用的所有参数必须匹配并由脚本识别，并且每个参数都具有关联的设置。这方面的一个例子是我在文件中定义的第一个参数是（模式），其设置是（LAN）。 For / f循环（其中两个）的编写方式以及编写配置文件的方式将使用var！count将所有使用的参数分配给（var＃）编号！在运行中，相关的设置将分配给（avar＃）。
然而，由于参数可以按任何顺序列出，唯一的要求是相关设置在同一行上，在其分隔符号之后，附加到var / avar的数字仅用于确保所有内容都存储在唯一中变量
然后我尝试使用＆＃34;如果＆＃34;将存储在循环正在处理的var＃中的参数与对项目有用的已知值匹配，例如
var1 = Mode avar1=LAN as set by the For /f loop
if var!count!==Mode ( SET Mode=avar!count! )
有希望匹配var1的参数Mode存储在里面，所以Mode变量应设置为avar1（Lan）中存储的任何内容（var1与avar1相同，var2与avar2相同，依此类推等等） ）
问题是if语句永远不会评估为true。下面是一个简化的代码示例，我甚至为了测试的目的，手动将var1设置在顶部附近，即使这应该由For / F循环完成并且它仍然没有评估为真
setlocal EnableDelayedExpansion

对于那些提到有关EOF的人，我认为它在没有标签的情况下作为功能的结束，但至少有一次我运行它，它似乎没有工作（虽然它可能是IF语句失败不合时宜（已经发生过几次））

我正在通过winbuilder创建一个Windows 10 PE解决方案，最终我希望它可以从至少3种方法中使用（直接来自闪存驱动器/ DVD，通过名为easy2boot的实用程序进行多重启动，以及PXE启动来自网络）。然而，我实现的大部分功能都需要一些额外的文件才能在驱动器号Y：上访问，但是根据你的启动方式，这可能意味着安装图像文件，安装网络共享，或只是读取你启动的闪存驱动器或DVD从
因此我正在编写一个在shell启动时加载之前运行的脚本。它做的第一件事就是检查每个驱动器的根目录以查找配置文件，如果可用，它可以进入城镇，如果不可用，则会提示用户回答一些问题并从那里开始。
我一直在写我要称之为的简单脚本＆＃39;多年来，这是他们如何运行的静态和线性，这是我第一次真正尝试我将称之为“动态脚本”＃39;它具有模块化子程序和循环，所有路径都是相对的，或者是用户提示但不是硬编码的。
我为其编写的主要脚本非常适合自己和现在大部分完成的LAN子例程，并且很好地回显了E2B和Flash子例程的占位符文本。
我目前正在研究检查配置文件的子例程，并运行该用户输入。我觉得一切都进入脚本顶空忘记测试了一段时间......
...当我做测试时，我发现＆＃34; IF＆＃34;我正在使用的语句永远不会评估为true，即使我手动设置变量并知道它是匹配的。我已经尝试了所有我能用引号思考的排列，没有，百分比和感叹号，空格，没有空格和不同的放置可能性......谷歌搜索和谷歌搜索和我在这里发现的一篇文章似乎应该有效但我没有尝试过从它起作用，但它激励我在这里问！
以下是为了简化开发而硬编码，以便在我的驱动器的根目录中查找配置文件，我计划将其放入的主脚本有一个＆＃34;如果存在＆＃34;循环遍历所有驱动器号以在任何驱动器上找到它。此外，我对此脚本发表了评论，不仅解释了什么做了什么，而且还说明了我遇到麻烦的地方。我还评论了一些重复的事情，这些是我实验的结果。现在的脚本将读取预期值并将它们分配给递增的变量并回显它们以显示其工作，但是当它尝试确定已读取的内容并将它们分配给要在其中使用的适当变量时失败让事情发生

if var!count!==Share (
将被解析为
if var1==Share (
假设count的值为1。
IF非常字面 - 比较运算符两侧的两个字符串按字面比较，因此指令为＆＃34;如果字符串 var1等于文字字符串分享＆＃34;
您需要 var1的内容，即!var%count%!这是 - 两个阶段 - 首先用内容{{1}替换任何%count%然后检索结果的内容。
这就是为什么count不应该用于一般!var!的情况，而是保留在需要这个两阶段解析的地方以及在循环中改变所需变量的时候。< / p>
BTW - value of a variable有一个if开关，可以使比较不区分大小写。
/i将列出所有变量，从set var
var预先定义为＆＃34;文件结尾＆＃34;。 :EOF预定义为＆＃34;转到文件结尾＆＃34; （即退出当前例程）如果您定义自己的标签goto :eof，则可能会遇到问题 - 例如，:eof很乐意到达您的标签，但goto eof将退出例程（我不能使用goto :eof语法的另一个原因）
