我正在试用.fsx脚本中的预编译正则表达式。但我不知道如何为生成的程序集指定.dll文件位置。我已经尝试在Regex.CompileToAssembly使用的AssemblyName实例上设置CodeBase等属性,但无济于事。下面是我有:Regex.CompileToAssembly如何设置.dll文件位置

open System.Text.RegularExpressions 

let rcis = [| 
    new RegexCompilationInfo(
     @"^NumericLiteral([QRZING])$", 
     RegexOptions.None, 
     "NumericLiteral", 
     "Swensen.Unquote.Regex", 
     true 
    ); 
|] 

let an = new System.Reflection.AssemblyName("Unquote.Regex"); 
an.CodeBase <- __SOURCE_DIRECTORY__ + "\\" + "Unquote.Regex.dll" 
Regex.CompileToAssembly(rcis, an) 

我在FSI执行此,当我评价an我看到:

> an;; 
val it : System.Reflection.AssemblyName = 
    Unquote.Regex 
    {CodeBase = "C:\Users\Stephen\Documents\Visual Studio 2010\Projects\Unquote\code\Unquote\Unquote.Regex.dll"; 
    CultureInfo = null; 
    EscapedCodeBase = "C:%5CUsers%5CStephen%5CDocuments%5CVisual%20Studio%202010%5CProjects%5CUnquote%5Ccode%5CUnquote%5CUnquote.Regex.dll"; 
    Flags = None; 
    FullName = "Unquote.Regex"; 
    HashAlgorithm = None; 
    KeyPair = null; 
    Name = "Unquote.Regex"; 
    ProcessorArchitecture = None; 
    Version = null; 
    VersionCompatibility = SameMachine;} 

但同样,我没有看到C:\用户\斯蒂芬\ Documents \ Visual Studio 2010 \ Projects \ Unquote \ code \ Unquote \ Unquote.Regex.dll就像我想要的。如果我搜索我的C驱动器Unquote.Regex.dll,我确实在某个临时AppData文件夹中找到了它。

那么,如何正确指定由Regex.CompileToAssembly生成的程序集的.dll文件位置?

似乎CompileToAssembly不尊重CodeBase或AssemblyName中的任何其他属性,而是将结果程序集保存到当前目录。尝试将System.Environment.CurrentDirectory设置为正确的位置,并在保存后将其恢复。

open System.Text.RegularExpressions 

type Regex with 
    static member CompileToAssembly(rcis, an, targetFolder) = 
     let current = System.Environment.CurrentDirectory 
     System.Environment.CurrentDirectory <- targetFolder 
     try 
      Regex.CompileToAssembly(rcis, an) 
     finally 
      System.Environment.CurrentDirectory <- current 


let rcis = [| 
    new RegexCompilationInfo(
     @"^NumericLiteral([QRZING])$", 
     RegexOptions.None, 
     "NumericLiteral", 
     "Swensen.Unquote.Regex", 
     true 
    ); 
|] 

let an = new System.Reflection.AssemblyName("Unquote.Regex"); 
Regex.CompileToAssembly(rcis, an, __SOURCE_DIRECTORY__) 
+0

非常好 - 谢谢! – 2012-04-15 18:26:24
