Error: Does not contain a method named 'op_Addition'

 

You will get an error while combining/merging two or more [String[]] of arrays which are stored in different variables. 

$variable1 = import-csv "x:\users1.csv"
$variable2 = import-csv "x:\users1.csv"
$variable3 = import-csv "x:\users1.csv"

$finalVariable = $variable1  + $variable12 + $variable13

Error: Does not contain a method named 'op_Addition'

Solution:

$finalVariable = @()

$variable1 = import-csv "x:\users1.csv"

$variable2 = import-csv "x:\users1.csv"

$variable3 = import-csv "x:\users1.csv"

$finalVariable = @($variable1)+@($variable2)+@($variable3)
