Powershell 动态循环浏览文本文件并获取常见匹配项

我有一个将数据输出到文本文件的脚本。现在我需要一种方法来获得与项目匹配的行数，并获得一个计数。我知道如何通过这样做得到一个值的计数

$ProjectMatches = Select-String -InputObject $FileContent -Pattern "PROJECT ID FOAH834" -AllMatches

但是我需要遍历文本文件，获取每个

项目ID SOMEPROJECTNUMBER

的计数，并获取每个项目的计数，然后将这些结果导出到csv文件。我的目标是展示每个项目投入了多少时间。每次参赛时间为15分钟

This 15 minutes is dedicated to PROJECT ID FOAH834
11/2/2017 8:07:36 PM
This 15 minutes is dedicated to PROJECT ID FOAH834
11/2/2017 8:07:38 PM
This 15 minutes is dedicated to PROJECT ID FOAH841
11/2/2017 8:10:15 PM
This 15 minutes is dedicated to PROJECT ID FOAH18
11/2/2017 8:10:17 PM
This 15 minutes is dedicated to PROJECT ID FOAH690
11/2/2017 8:10:21 PM
This 15 minutes is dedicated to PROJECT ID PRJ0036909

您可能希望先进行一些正则表达式匹配，然后再进行字符串操作，而不是对所有值进行硬编码

我会用像这样的东西

$matches = [regex]:matches($FileContent,"PROJECT ID .*<br/>")

foreach($entry in $hashtable.keys){
    write-output "$entry: $($hashtable[$entry])"
}

然后，您可以使用以下方法处理哈希表

$matches = [regex]:matches($FileContent,"PROJECT ID .*<br/>")

foreach($entry in $hashtable.keys){
    write-output "$entry: $($hashtable[$entry])"
}
