dotnet的CSharpScript的测试案例

场景

想找一个支持跨平台的dotnet脚本代码引擎。

总结

• 增加CSharpScript后，windows/linux平台的编译包会增大20MB；
• 编译后的单文件模式，在windows/linux无法运行，原因未知（猜测和Roslyn需要本地有SDK有关）；
• 遂放弃使用；

测试代码

// See https://aka.ms/new-console-template for more information

using Microsoft.CodeAnalysis.CSharp.Scripting;
using Microsoft.CodeAnalysis.Scripting;

Console.WriteLine("Hello, World!");



var result = await CSharpScript.EvaluateAsync("1 + 2");
Console.WriteLine(result); // 输出 3

var state = await CSharpScript.RunAsync("int x = 1;");
state = await state.ContinueWithAsync("int y = 2;");
state = await state.ContinueWithAsync("x + y");
Console.WriteLine(state.ReturnValue); // 输出 3

var options = ScriptOptions.Default
    .WithReferences(typeof(DateTime).Assembly)
    .WithImports("System");

var result2 = await CSharpScript.EvaluateAsync<DateTime>(
    "DateTime.Now.AddDays(1)",
    options);
Console.WriteLine(result2.ToString()); // 输出 3



try
{
    var result5 = await CSharpScript.EvaluateAsync("1 + ");
}
catch (CompilationErrorException e)
{
    Console.WriteLine(string.Join(Environment.NewLine, e.Diagnostics));
}

var result4 = await CSharpScript.EvaluateAsync<string>(@"
    int day = 3;
    switch (day) 
    {
        case 1: return ""Monday"";
        case 2: return ""Tuesday"";
        case 3: return ""Wednesday"";
        default: return ""Invalid day"";
    }
");
Console.WriteLine(result4); // 输出 "Wednesday"


var result6 = await CSharpScript.EvaluateAsync<int>(@"
    int x = 10;
    if (x > 5) 
    {
        return x * 2;
    }
    else 
    {
        return x / 2;
    }
");
Console.WriteLine(result6); // 输出 20

Console.ReadLine();
