String.Format不打印值

Question

这段代码不会打印价值年份，我无法弄清楚原因。

String words = string.Format("{0,-60}" + "|" + "{0,-7}" + "|" + "{0,-20}"  + 
"|" + "{0,-20}", Title, Year, Album, Artist);

其他所有工作，如果我打印每个值没有像这样的格式，它工作正常

String words = string.Format(Title + ", " + Year + ", " + album + ", " + 
Author); //works 

Answer 1

你拥有它的方式只是在格式字符串中引用了Title参数。试试

String words = string.Format("{0,-60}" + "|" + "{1,-7}" + "|" + "{2,-20}"  + 
"|" + "{3,-20}", Title, Year, Album, Artist);
