![]() Recently, we faced a problem: the PowerShell cmdlet returns a number in a variable of String type. When you are performing various actions on a variable, PowerShell can automatically determine the variable type, but this doesn’t always work accurately. How to Convert String to Integer in PowerShell? PowerShell will try to figure it out on its own. When you create a variable, you don’t have any need to specify its type. This means you don’t need to declare variables and set specific data types before using them. PowerShell belongs to a weak, dynamic typed language class. The printed characters to the right are of limited usefulness, because they are the byte-individual interpretation of the input bytes, which only renders characters in the 8-bit range as expected (code points <= U+00FF) a 0x0 byte is represented as a. ![]() ![]() NET string use Unicode (UTF16-LE) - so that the invariably byte-oriented display shows the high byte of the 16-bit code units first, which reads more naturally.īyte pair 20 0E is the first code unit, U+200E (the left-to-right mark), and 00 35 the second one, U+0035 (the digit 5). Encoding BigEndianUnicode (UTF16-BE) is used - even though. You can also use Format-Hex, but the format isn't easy to parse visually: PS> $intStr | Format-Hex -Encoding BigEndianUnicodeĠ0 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F Optional reading: Examining a string's characters: # Print the code points of the string's characters:Ĩ206 # decimal equivalent of 0x200e, the LEFT-TO-RIGHT-MARKĥ3 # decimal equivalent of 0x54, the DIGIT FIVE # Note the required (.) for proper precedence. "Input string was not in a correct format." # FAILS, due to the invisible Unicode char. from the string: # Simulate the input string with the invisible control char. Removing that character will make the conversion succeed, which in the simplest case is achieved by simply eliminating all non-digit chars. Here is the output of a Format-Hex: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0FĮxamining the error messages in your question's source text reveals that your string contains the invisible LEFT-TO-RIGHT-MARK Unicode character ( U+200E), which is why the conversion fails. But I have no idea what I could be doing wrong, as the GetType() says it is indeed a string.ĮDIT: Per TobyU's answer, I've also tried $intVar = $intVar, with the same result ofĮxception calling "Parse" with "1" argument(s): "Input string was not in a correct format."ĮDIT 3: So apparently, as some commenters mentioned, there are invalid characters. If I manually assign $intVar a value of "5" ( $intVar = "5") everything works just fine, so I think there must be an issue with how I'm getting the value. Error: "Input string was not in a correct format." Next method: $converted = ::ToInt32($intVar, 10)Įxception calling "ToInt32" with "2" argument(s): "Could not find any recognizable digits."Īnd the third method I've tried: $converted = $intVar / 1Ĭannot convert value "5" to type "System.Int32". Here's the first method I've tried for conversion: $converted = 0 just to ensure validity: $obj = (New-Object -TypeName PSCustomObject -Property = $com.GetDetailsOf($_, 155).toString().trim() However, it keeps on telling me that I don't have a valid number, even though I'm sure I do.įirst of all, here's how I'm getting my variable, and a printout of the type, etc. I'm attempting to convert a string to an integer using PowerShell.
