Using PowerShell and .NET Framework Class to Open a File Dialog Box

Using PowerShell script to open a file dialog:

<SCRIPT >
[reflection.assembly]::loadwithpartialname(“System.Windows.Forms”) | Out-Null
$openFile = New-Object System.Windows.Forms.OpenFileDialog
$openFile.Filter = “txt files (*.txt)|*.txt|All files (*.*)|*.*” 
If($openFile.ShowDialog() -eq “OK”
{
   get-content $openFile.FileName
}
</SCRIPT >

ShowDialog() returns a DialogResult Enumeration of either an OK or Cancel. Since you can’t click OK in the dialog until you pick a file, you also get some validation in the process. Once the file is selected and the user clicks the Open button in the dialog, you pass the path to the Get-Content cmdlet on the last line and resume your PowerShell script.
