You can use ToCharArray and where to find the matches. For example, to count the number of "e" in the file you can say:

$file = get-item ''

$reader = New-Object -TypeName System.IO.StreamReader -ArgumentList $file

[int]$count = 0

while ( $read = $reader.ReadLine() ) {

    $matches = ($read.ToCharArray() | where {$_ -eq 'e'}).Count
    $count = $count + $matches
}
