100分请教java.text.DecimalFormat和c＃里的那个class相对应

ken1024 2004-07-13 01:59:26

从java转换成c＃的时候报如下错：

//UPGRADE_ISSUE: Class“java.text.DecimalFormat” 未转换。. 'ms-help://MS.VSCC.2003/commoner/redir/redirect.htm?keyword="jlca1000_javatextDecimalFormat"'

DecimalFormat tDecimalFormat = new DecimalFormat("#############.#####");
System.String tStr = tDecimalFormat.FormatDouble(aValue);

提示说该用 String.Format 和包含在 System.Globalization 命名空间的类中的可自定义的格式模式。
可是上面的两行代码具体该怎么写？请达人解答！
一旦解决，立即结贴！
在线等待～～～谢谢各位！

Double myDouble = 1234567890;
String myString = myDouble.ToString( "(###) ### - ####" );
// The value of myString is "(123) 456 – 7890".

呵呵，给了我这么长，我想问一下，就是下面这两行代码如何转换：？
DecimalFormat tDecimalFormat = new DecimalFormat("#############.#####");
System.String tStr = tDecimalFormat.FormatDouble(aValue);

就是让指定的 tStr按照#############.#####的格式输出
谢谢～！
