Visual Studio 2015中的C#7.0``变量'' [英] C# 7.0 'out variables' in Visual Studio 2015

问题描述

我想在Visual Studio 2015中编译C#7.0解决方案，但出现语法错误:

I would like to compile C# 7.0 solution in Visual Studio 2015, but I have syntax error:

错误

ErrorMessage:'DateTime'是一种类型，但用作变量.

ErrorMessage : 'DateTime' is a type but is used like a variable.

这与在C#7.0中更改的输出变量"有关

This is related to 'out variables' changed in C# 7.0

很遗憾，我无法使用VS2017(社区)和此教程-不起作用(master分支现在适用于VS2017).

Unfortunately I can not use VS2017 (community) and THIS TUTORIAL - not working (master branch is adapted to VS2017 now).

您有解决此问题的想法吗?

Do you have an idea how to solve this problem?

推荐答案

您只需要在调用外部声明一个DateTime变量，并使用out关键字传递参数，如下所示:

You just need to declare a DateTime variable outside the call and pass the parameter with the out keyword like this:

DateTime yuorParam;
method( ..., ..., out yourParam);
