June 17 Calling a Web Service from PowerShellBefore starting this you need to setup PS environment to enable the Visual Studio 2005 tools. Copy the following into a file called something like vs80vars.ps1:
$env:VSINSTALLDIR="$env:ProgramFiles\Microsoft Visual Studio 8"
$env:VCINSTALLDIR="$env:ProgramFiles\Microsoft Visual Studio 8\VC" $env:DevEnvDir="$env:VSINSTALLDIR\Common7\IDE" $env:FrameworkSDKDir="$env:VSINSTALLDIR\SDK\v2.0" $FrameworkPath=$([System.Runtime.InteropServices.RuntimeEnvironment]::GetRuntimeDirectory())
$env:FrameworkDir=$(split-path $FrameworkPath -Parent) $env:FrameworkVersion=$(split-path $FrameworkPath -Leaf) $env:PATH="$env:VSINSTALLDIR\Common7\IDE;$env:VCINSTALLDIR\BIN;$env:VSINSTALLDIR\Common7\Tools;$env:VSINSTALLDIR\Common7\Tools\bin;$env:VCINSTALLDIR\PlatformSDK\bin;$env:FrameworkSDKDir\bin;$env:FrameworkDir\$env:FrameworkVersion;$env:VCINSTALLDIR\VCPackages;$env:PATH"
$env:INCLUDE="$env:VCINSTALLDIR\ATLMFC\INCLUDE;$env:VCINSTALLDIR\INCLUDE;$env:VCINSTALLDIR\PlatformSDK\include;$env:FrameworkSDKDir\include;$env:INCLUDE" $env:LIB="$env:VCINSTALLDIR\ATLMFC\LIB;$env:VCINSTALLDIR\LIB;$env:VCINSTALLDIR\PlatformSDK\lib;$env:FrameworkSDKDir\lib;$env:LIB" $env:LIBPATH="$FrameworkPath;$env:VCINSTALLDIR\ATLMFC\LIB" Then "dot" the attached PS1 script into your shell like so"
PoSH 1> . .\vs80vars.ps1
Now here's how to acces one particular web service. Note that the first two lines below create a proxy assembly which takes care of the communication to the web service. On line 3 and 4 we load the assembly and then create the WeatherForecast proxy object. Then on line 5 we call one of its methods. It returns an XML document which we store in $forecast. BTW, you can use Reflector or Visual Studio's Object Browser to see the other methods in the assembly (or you can open the WeatherForecast.cs file to see the nitty gritty proxy details).
PoSH 1> wsdl.exe http://www.webservicex.net/WeatherForecast.asmx?WSDL
PoSH 2> csc /t:library WeatherForecast.cs
PoSH 3> [Reflection.Assembly]::LoadFrom("$pwd\WeatherForecast.dll")
PoSH 4> $weatherService = new-object WeatherForecast
PoSH 5> $forecast = $weatherService.GetWeatherByZipCode(80526)
PoSH 6> $forecast

Updated 12/27/2006: If you are behind a corporate firewall you might need to run WSDL.exe with additional options:
wsdl.exe http://www.webservicex.net/WeatherForecast.asmx? /proxy=myproxyserver:8080
/proxyusername=myusername /proxypassword=mypassword /proxydomain=USA Thanks to sundanceca for figuring the proxy options to do this. Comments (4)
