课程和成绩未显示在C#控制台中
本文关键字：控制台 显示 | 更新日期: 2023-09-27 18:27:11
我有接受用户名和主题标记的代码。我想以表格结构显示课程、分数和成绩，但没有显示数据。
你能解释一下如何将数据放在表格格式中吗？例如：｛1,13｝

您调用了错误的WriteLine重载来使用格式化功能，您需要将格式作为第一个参数传递的重载，之后的所有内容都是值。
例如，您可以更改以下行：
Console.WriteLine("|", csharp, "|{0,6} |{1,13}|{2,13}|", A, A * CHours, "|");
类似的东西：
Console.WriteLine("|{0}|{1,6}|{2,13}|", csharp, A, A * CHours);
此外，如果您对表格的对齐有问题，您可能需要在此处查找解决方案。
Console.WriteLine的第一个参数是一个格式字符串，以下参数是插入字符串中的参数。示例：
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。
您也可以只使用长度{1,15}或格式{1:N2}。右对齐使用正长度，左对齐使用负长度。
如果您使用的是Visual Studio 15，还可以使用新的字符串插值功能。与上面相同的例子可以这样写：
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。
