Hi Krishna,

According to your description, you want to know the max length of a PowerShell string variable.

Strings in PowerShell (and most of the other programming languages) are of "Fixed length" or immutable (they cannot change). .net also offers a mutable string object System.Text.StringBuilder, which should be your preference if you change the string a lot through out its lifetime.

The theoretical max length of a String is 2147483647, but you are more likely to run out of memory before you ever reach that limit.

This will show the maximum length:

$s = New-Object Text.StringBuilder "test"
$s.MaxCapacity

Best Regards,

CY

The Memory restrictions aside, Strings cannot have more than 2³⁰ (1,073,741,824) characters, since a 2GB limit is imposed by the Microsoft CLR (Common Language Runtime).
