C# CsScript with Mono：如何使Mono不将警告视为错误

我使用CSScriptLibrary.dll在运行于Windows和Linux的应用程序中执行C#代码。问题是，现在，我需要使用

#pragma disable warning

来禁用可能出现的各种警告，以便让脚本在Mono上编译，这是一种非常丑陋的攻击

// the following simple script will not execute on Mono due to a warning that a is not used.
var code = "public class Script { public object Run() { var a=1; return 2+3; }}"
// here is how the script is executed using CsScriptLibrary
try
{
    var asm = new AsmHelper(CSScript.LoadCode(code, "cs", null, true));
    // if we reach that point, the script compiled
    var obj = asm.CreateAndAlignToInterface<IScript>("*");
    // now run it:
    var result=obj.Run();
}
catch (CompilerException e)
{
    // on .net compiler exceptions are only raised when there are errors
    // on mono I get an exception here, even for warnings like unused variable
}    

但是我没有成功，我甚至不确定这是不是正确的道路。无论如何，为了完整起见，我在这里注意到，CSScript中的

CSScript.GlobalSettings.DefaultArguments

默认为

/c/sconfig/co:/warn:0

有人知道如何让CSScript.LoadCode忽略Mono上的警告或至少不将其视为错误吗？

这里有两种解决方案（在Oleg Shilo的帮助下找到）。您可以在脚本中直接包含所需的编译器选项：

//css_co -warn:0 
using System;
...

或者您可以将

CSScript.LoadCode

替换为

LoadWithConfig

，这允许直接传递编译器选项。大概是这样的：

static public Assembly LoadCode(string scriptText, bool debugBuild, params string[] refAssemblies)
{
    string tempFile =  System.IO.Path.GetTempPath() + Guid.NewGuid().ToString() +".cs";        
    try
    {
        using (StreamWriter sw = new StreamWriter(tempFile))
            sw.Write(scriptText);        
        return LoadWithConfig(scriptFile, null, debugBuild, CSScript.GlobalSettings, "-warn:0", refAssemblies);
    }
    finally
    {
        if (!debugBuild)
        {
            //delete temp file
        }
    }
}

应该注意的是，第二个解决方案将绕过在LoadCode中执行的内置程序集缓存。不过，缓存已编译的脚本对象很容易

static public Assembly LoadCode(string scriptText, bool debugBuild, params string[] refAssemblies)
{
    string tempFile =  System.IO.Path.GetTempPath() + Guid.NewGuid().ToString() +".cs";        
    try
    {
        using (StreamWriter sw = new StreamWriter(tempFile))
            sw.Write(scriptText);        
        return LoadWithConfig(scriptFile, null, debugBuild, CSScript.GlobalSettings, "-warn:0", refAssemblies);
    }
    finally
    {
        if (!debugBuild)
        {
            //delete temp file
        }
    }
}
