c# - new Version(AssemblyFileVersionAttribute.Version) 总是会成功吗？

Question

new Version(AssemblyFileVersionAttribute.Version) 总是会成功吗？

这是我的代码。

Contract.Ensures(Contract.Result<Version>() != null);
var ass = Assembly.GetExecutingAssembly();
var attributes = ass.GetCustomAttributes(typeof(AssemblyFileVersionAttribute), false).Cast<AssemblyFileVersionAttribute>();
var versionAttribute = attributes.Single();
return new Version(versionAttribute.Version)

Answer 1

否:

[assembly:AssemblyFileVersion("fred")]
static class program
{
    static void Main()
    {
        var ass = Assembly.GetExecutingAssembly();
        var attributes = ass.GetCustomAttributes(typeof(AssemblyFileVersionAttribute), false).Cast<AssemblyFileVersionAttribute>();
        var versionAttribute = attributes.Single();
        var ver = new Version(versionAttribute.Version);        
    }
}

请注意，这确实会生成一个警告:

Warning 1 Assembly generation -- The version 'Fred' specified for the 'file version' is not in the normal 'major.minor.build.revision' format

但是警告并不能阻止它发生。
