的String.Format在C＃不返回修改的int值 [英] String.Format in C# not returning modified int value

问题描述

我特林返回与值内逗号seperators一个int值。

I am tring to return an int value with comma seperators within the value.

12345将返回为12345

12345 would be returned as 12,345

该follwing代码工作：

The follwing code works:

int myInt = 1234567;
MessageBox.Show(string.Format("My number is {0}", myInt.ToString("#,#")));

12345如预期显示。

12,345 is displayed as expected.

而下面的代码确实没有工作，但是从我读什么，应该工作：

While the following code does no work, but from what I am reading, should work:

int myInt = 1234567;
MessageBox.Show(string.Format("My number is {0:#,#}", myInt.ToString()));

12345显示。

12345 is displayed.

你能帮助我理解为什么第二组的代码是不工作？

Can you help me understand why the second set of code is not working?

感谢

推荐答案

您不应该的ToString 格式之前，INT。试试这个：

You shouldn't ToString the int before the format. Try this:

MessageBox.Show(string.Format("My number is {0:#,#}", myInt));
