使用C#在Exchange 2010上创建邮箱

我试图通过我的C#windows应用程序在Exchange 2010上创建用户邮箱。 这是我的代码

PSCredential creds = new PSCredential("user id", StringToSecureString("password")); System.Uri uri = new Uri("http://servername/powershell?serializationLevel=Full"); Runspace runspace = RunspaceFactory.CreateRunspace(); PowerShell powershell = PowerShell.Create(); PSCommand command = new PSCommand(); command.AddCommand("New-PSSession"); command.AddParameter("ConfigurationName", "Microsoft.Exchange"); command.AddParameter("ConnectionUri", uri); command.AddParameter("Credential", creds); command.AddParameter("Authentication", "Default"); powershell.Commands = command; runspace.Open(); powershell.Runspace = runspace; Collection result = powershell.Invoke(); powershell = PowerShell.Create(); command = new PSCommand(); command.AddCommand("Set-Variable"); command.AddParameter("Name", "ra"); command.AddParameter("Value", result[0]); powershell.Commands = command; powershell.Runspace = runspace; powershell.Invoke(); powershell = PowerShell.Create(); command = new PSCommand(); command.AddScript("Import-PSSession -Session $ra"); powershell.Commands = command; powershell.Runspace = runspace; powershell.Invoke(); powershell = PowerShell.Create(); command.AddCommand("Invoke-Command"); command.AddParameter("ScriptBlock", System.Management.Automation.ScriptBlock.Create("New-Mailbox")); command.AddParameter("Name", "FnameLname"); command.AddParameter("Password", "abcd@123"); command.AddParameter("Alias", "FLname"); command.AddParameter("OrganizationalUnit", "Company/OU"); command.AddParameter("UserPrincipalName", "Fname.Lname@Domain.com"); command.AddParameter("SamAccountName", "FLname"); command.AddParameter("FirstName", "Fname"); command.AddParameter("Initials", "FL"); command.AddParameter("LastName", "Lname"); command.AddParameter("Database", "dbname"); command.AddParameter("LinkedMasterAccount", @"company\FLname"); command.AddParameter("LinkedDomainController", "domain controller"); powershell.Commands = command; powershell.Runspace = runspace; var createmailbox = powershell.Invoke(); 

但是当我执行上面的代码时,我得到以下错误。

找不到与参数名称“名称”匹配的参数
