Edw*_*uay 13 c# arrays casting decimal
如何定义一个小数组而不显式地每个小数组?
//decimal[] prices = { 39.99, 29.99, 29.99, 19.99, 49.99 }; //can't convert double to decimal
//var prices = { 39.99, 29.99, 29.99, 19.99, 49.99 }; //can't initialize...
decimal[] prices = { (decimal)39.99, (decimal)29.99, (decimal)29.99, (decimal)19.99, (decimal)49.99 };

使用m后缀.
decimal[] prices = { 39.99m, 29.99m, 19.99m, 49.99m };

如果没有m(或M)后缀,编译器会将其视为double.
