所以我想弄清楚如何在我的程序中打印一个保龄球名称和分数列表。使用控制台时很简单。我想弄清楚如何将数组打印到GUI上的标签？有什么建议？我试过if / else if语句，但显然它不起作用。
这是我的表单代码：

答案 0 :(得分：0)
作为一般解决方案，我建议使用LINQ输出每个项目一个String的列表，然后使用String.Join将它们合并为一个String最简洁的选择，例如
myLabel.Text = string.Join(Environment.NewLine, myArray.Select(obj => string.Format("{0}, {1}", obj.Property1, obj.Property2)));
