所在位置 行:9 字符: 1
+ $Connetion.Open()
+ ~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : SqlException

2、解决


3、连接代码

$SqlServerNname="xxxx"
$SqlDatabaseName='FileInfo'
$SqlTableName='FolderInfo'
$SqlUser='sa'
$SqlUserPwd='xxxxxxxRlKnH'
$Connetion=New-Object System.Data.SqlClient.SqlConnection
$Connetion.ConnectionString="Server = $SqlServerNname;Initial Catalog = $SqlDatabaseName;Integrated Security = false;User ID = $SqlUser;Password = $SqlUserPwd;"
$Connetion.Open()
