String.Format 不打印值

Question

此代码不会打印值年份，我不知道为什么。

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

其他一切正常，如果我打印每个值而不像这样格式化，它工作正常

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

Answer 1

按照您的方式，您只在格式字符串中引用了 Title 参数。尝试 String words = string.Format("{0,-60}" + "|" + "{1,-7}" + "|" + "{2,-20}" + "|" + "{3,-20}", Title, Year, Album, Artist);
