Hi,

catch(Exception ex)
{
}
will just ignore any error that could happen. Just get rid of that...

Where is your script ? For a web app, it is likely the "current directory" is not what you expect. If PowershellScript is a folder under your web site try :

shell.Commands.AddScript(Server.MapPath("/~PowershellScript/test.ps1"));

Server.MapPath will return something such as "c:\somewhere\yoursiteroofolder\PowershellScript\test.ps1" ie it get the physical path for a a file on your site.

Changed the code and getting the error as below

[HttpException (0x80004005): 'D:/Inetpub/wwwroot/PowershellScript/test.ps1' is a physical path, but a virtual path was expected.] System.Web.Util.UrlPath.CheckValidVirtualPath(String path) +9830644 System.Web.Util.UrlPath.Combine(String appPath, String basepath, String relative) +132

string sourceFile = Server.MapPath(@"D:\Inetpub\wwwroot\PowershellScript\test.ps1");
var shell = PowerShell.Create();
shell.Commands.AddScript(Server.MapPath("/~PowershellScript/test.ps1"));
shell.Invoke();

Hi manusan,

According to your description, you should add a virtual path in Server.MapPath() method. You should firstly save test.ps1 in the same  folder  with your asp page in your application. Then you could use server.MapPath() to find it physical path. You could see as below:

string sourceFile = Server.MapPath("/test.ps1");

Here is the link,I hope it could help you.

Server.MapPath(@"D:\Inetpub\wwwroot\PowershellScript\test.ps1") doesn't make sense. You provide a path relative to your web app and it returns its physical path ie :

Server.MapPath("/~PowershellScript/test.ps1") should return something such as "D:\Inetpub\wwwroot\PowershellScript\test.ps1" so it could be :

string sourceFile = Server.MapPath("/~PowershellScript/test.ps1");
var shell = PowerShell.Create();
shell.Commands.AddScript(sourceFile);
shell.Invoke();

Or you could populate sourceFile directly from some configurartion information (or the root directorty for your ps scripts) if you store them at some other place which is not under the web site root.
