我创建了一个实现Microsoft.Data.Schema.ScriptDom和Microsoft.Data.Schema.ScriptDom.Sql接口的基本C#类。这两个程序集是Visual Studio Database Edition(VSDB)的一部分,是解析/脚本API。您可以解析SQL文本并输出格式SQL脚本。有关VSDB程序集的更多信息,请参阅this blog post。由于它们是可再发行的,因此我已经包含了程序集和PowerShell脚本here

我正在使用PowerShell V2 add-type来创建运行时类型。我在3台不同的机器上测试了脚本。在一台机器上,脚本在其他两台机器上按预期工作,产生以下错误。两个引用的程序集都与PowerShell脚本放在同一个文件夹中。关于我做错了什么想法?

非常简单,一旦你知道; - )

Max的示例有效,因为这些程序集位于GAC中,因此可以按名称引用它们。您的程序集不是,因此需要通过路径引用它们。

您不需要顶部的Add-Type引用,至少不需要该脚本 - 只需将最后几行更改为:

$PSScriptRoot = (Split-Path $MyInvocation.MyCommand.Path -Parent)
$refs = @("$PSScriptRoot\Microsoft.Data.Schema.ScriptDom.dll","$PSScriptRoot\Microsoft.Data.Schema.ScriptDom.Sql.dll")
add-type -ReferencedAssemblies $refs -TypeDefinition $Source -Language CSharpVersion3 -passThru

答案 1 :(得分:2)

如果您将VSTSDB程序集放在与脚本相同的目录中,那么您不想使用“。”在一条相对的道路上。 “”将相对于调用脚本的目录。尝试这样的事情:

$ScriptDir = Split-Path $MyInvocation.MyCommand.Path -Parent
Add-Type -Path "$ScriptDir\Microsoft.Data.Schema.ScriptDom.dll"

答案 2 :(得分:2)

我有一个我在PS赛道上使用过的样本。这有点基本但有效。这是使用SMO的代码:

$Assem = ("Microsoft.SqlServer.Smo","Microsoft.SqlServer.ConnectionInfo")
$Source = @"
public class MyMSSql
{
       public static string getEdition(string sqlName)
       {
           string sqlEdition;
           Microsoft.SqlServer.Management.Smo.Server sname = new Microsoft.SqlServer.Management.Smo.Server(sqlName);
           sqlEdition = sname.Information.Edition;
           return sqlEdition;
       }
       public string getSqlEdition(string sqlName)
       {
           string sqlEdition;
           Microsoft.SqlServer.Management.Smo.Server sname = new Microsoft.SqlServer.Management.Smo.Server(sqlName);
           sqlEdition = sname.Information.Edition;
           return sqlEdition;
       }

}
"@;
Add-Type -ReferencedAssemblies $Assem -TypeDefinition $Source
[MyMSSql]::getEdition("MAX-PCWIN1")
#Developer Edition (64-bit)

$MySQLobj = New-Object MyMSSql
$MySQLobj.getSqlEdition("MAX-PCWIN1")

希望这会给你一个提示。
