powershell - 连接两个csv文件，并在第三个csv文件上输出，输出不显示连接的值

Question

我有两个CSV文件output.csv和Roster.csv

“ output.csv ”具有以下 header

UserID, User, Department, City, Group, Phone, Mobile, Extension, Office, Manager, Email

“ Roster.csv ”具有此 header

BUNID

我想将 BUNID与 USERID匹配，并使用这些 header 生成输出

UserID, User, Department, City, Group, Phone, Mobile, Extension, Office, Manager, Email, BUNID 

问题是生成了输出，但BUNID字段是唯一空白的字段。

这是代码

$csv1 = Import-Csv "C:\CSVfiles\output.csv"
$csv2 = Import-csv "C:\CSVfiles\Roster.csv"

$Join = Join-Object -Left $csv1 -Right $csv2 -LeftJoinProperty UserID -RightJoinProperty BUNID -Type AllInLeft -RightProperties BUNID

$Join | select-object UserID, User, Department, City, Group, Phone, Mobile, Extension, Office, Manager, Email, BUNID | sort BUNID | Export-Csv "C:\CSVfiles\output_pas.csv"

在第三个CSV上输出这些字段。

UserID, User, Department, City, Group, Phone, Mobile, Extension, Office, Manager, Email, BUNID 

输出应包含output.csv中的所有数据，并与Roster.csv中的BUNID相匹配，类似于我们对vlookup所做的操作。

我知道我犯了一个业余错误，但无法理解。

Answer 1

这是合并两个CSV文件的一种方法。它不会进行传统的合并，因为它会添加$ Roster条目，而不是将其与$ UserID条目合并。
