如何确定我是在本地PC上运行还是在云上运行？

Question

使用MVC3,我想确定我是在本地运行还是部署到云端？

Answer 1

RoleEnvironment.IsAvailable 告诉您是否在Windows Azure中运行,但它没有区分真正的Windows Azure和本地开发模拟器.

我写了一篇博客文章,展示了一个技巧,可以确定你是在真实模拟和模拟Windows Azure中运行RoleEnvironment.IsAvailable == true- 希望这可以提供你正在寻找的东西.

编辑:如果你想要我在上述帖子中描述的下行代码,不解释为什么该技术有效:

private bool IsRunningInDevFabric()

    {
        // easiest check: try translate deployment ID into guid
        Guid guidId;
        if (Guid.TryParse(RoleEnvironment.DeploymentId, out guidId))
            return false;   // valid guid? We're in Azure Fabric
        return true;        // can't parse into guid? We're in Dev Fabric
    }

编辑2:我的回答有点过时了.现在RoleEnvironment.IsEmulated,使用起来要简单得多.MSDN文档在这里

Answer 2

这就是我使用的

public static class Azure
{
    private static bool m_IsRunningAzure = GetIsRunningInAzure();

    private static bool GetIsRunningInAzure()
    {
        Guid guidId;
        if (RoleEnvironment.IsAvailable && Guid.TryParse(RoleEnvironment.DeploymentId, out guidId))
            return true;   
        return false;      
    }

    public static bool IsRunningInAzure()
    {
        return m_IsRunningAzure; 
    }

    private static bool m_IsRunningAzureOrDevFabric = GetIsRunningInAzureOrDevFabric();

    private static bool GetIsRunningInAzureOrDevFabric()
    {
        return RoleEnvironment.IsAvailable;
    }

    public static bool IsRunningInAzureOrDevFabric()
    {
        return m_IsRunningAzureOrDevFabric;
    }
}
