使用PowerShell连接到SQL Server

Question

我使用下面的powershell脚本连接到sql server的实例。我很确定我的用户名和密码是正确的。

  

$ connectionString =“server = {0}; database = {1}; uid = {2}; pwd = {3};”

$c = Get-Credential
Write-Host($ipAddress)
Write-Host  $c.username 
Write-Host  $c.GetNetworkCredential().password

$connectionString = [string]::Format( "server={0};database={1};uid={2};pwd={3};", "servername", "databasename",$c.username,$c.GetNetworkCredential().password) 
#open database connection to SQL Server

Write-Host  $connectionString
$conn = New-Object system.Data.SqlClient.SqlConnection
$conn.connectionstring = $connectionString
$conn.open

    switch ($conn.State)
{
"Open" { Write-Host "Do some work"; }
Default { Write-Host "The connection is $($conn.State).  There has been an error connecting to the database."; }
}

它始终属于默认语句。

Answer 1

你对$ conn.open的调用缺少（），所以它会返回对该方法的引用而不是调用它。
