无法找到添加类型错误元文件

Question

我创建了一个基本的C#类,它实现了Microsoft.Data.Schema.ScriptDom和Microsoft.Data.Schema.ScriptDom.Sql接口.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,请参阅此博客文章.由于它们是可再发行,我既包括组件和PowerShell脚本在这里:

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.关于我做错了什么的任何想法？

很简单,一旦你知道;-)

Max的示例有效,因为这些程序集在GAC中,因此可以通过名称引用它们.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
