我的代码接受用户的名称和主题标记。我想在表结构中显示课程，标记和成绩，但数据没有显示。
您能否解释一下如何将数据放入表格格式，例如：{1,13}

答案 0 :(得分：3)
您正在调用WriteLine的错误重载以使用格式化功能，您希望将传递格式的格式作为第一个参数，并且后面的所有内容都是值。
例如，您可以更改此行：
Console.WriteLine("|", csharp, "|{0,6} |{1,13}|{2,13}|", A, A * CHours, "|");
To like like：
Console.WriteLine("|{0}|{1,6}|{2,13}|", csharp, A, A * CHours);
此外，如果您在对齐表时遇到问题，可能需要查看here以获得解决方案。

Console.WriteLine的第一个参数是格式字符串，以下参数是插入字符串中的参数。例如：
Console.WriteLine("A = {0}, B = {1}, C = {2}", a, b, c);
您还可以指定长度和格式，例如：{1,15:N2}
这意味着参数1（必须是数字类型）的长度为15个字符，格式为2位小数。
您也可以只使用{1,15}长度或{1:N2}格式。使用正长度进行右对齐，使用负长度进行左对齐。
如果您使用的是Visual Studio 15，还可以使用新的字符串插值功能。上面的例子可以写成：
Console.WriteLine($"A = {a}, B = {b}, C = {c}");
其中变量（和其他表达式）可以直接写入格式字符串。
