c# – Razor ViewEngine临时编译.cs文件

static void Main(string[] args)  
{
    var service = TemplateServiceFactory.CreateTemplateService(Language.CSharp,true);
    string result = "";
    try
    {
       result = service.Parse("Hello @DateTime.NowXX ");
    }
    catch (TemplateCompilationException ex)
    {
      foreach (var error in ex.Errors)
         if (!string.IsNullOrEmpty(error.FileName))
             Console.WriteLine( File.ReadAllText( error.FileName ));
    }  //                                         ^^^^ File does not exist!

    Console.WriteLine( result );       
    Console.ReadKey();
    }

RazorEngine的TemplateCompilationException是一个包含一个包含 CompilerError个对象的CompilerErrorCollection的类,因此您可能从TemplateCompilationException CompilerError对象获得的大部分细节都是它们各自的属性,这似乎足以进行调试.考虑并尝试这个例子

try
{
    Razor.Parse("My erroneous @DateTime.Now.foo()");
}
catch(TemplateCompilationException ex)
{
    foreach(var error in ex.Errors)
    {
        StringBuilder sb = new StringBuilder();
        sb.AppendLine("Compile Error Num: t" + error.ErrorNumber);
        sb.AppendLine("Error Text:nt" + error.ErrorText);
        Console.WriteLine(sb.ToString());
    }
    Console.WriteLine("Erroneous Template:nt" + ex.Template);
}

当我运行我的示例时,这就是我得到的,它告诉您遇到的错误,您可以转储模板数据以供用户参考.

Compile Error Num:   CS1061
Error Text:
  'System.DateTime' does not contain a definition for 'foo' and no 
  extension method     'foo' accepting a first argument of type 
  'System.DateTime' could be found (are you missing a using directive 
  or an assembly reference?)

Erroneous Template:
    My erroneous @DateTime.Now.foo()
