推荐答案
在VB中,
In VB,
Chr(13) = Carriage Return - (moves cursor to lefttmost side)
ChrW(13) = New Line (drops cursor down one line/ Enter)
组合两者都用于在新行的开头打字。

基本上,Chr(13)和ChrW(13)是相等的。
但是ChrW接受unicode字符,而Chr只接受ANSI并使用当前代码页将任何整数值从0转换为255到一个Char

不允许Chr(256),但是ChrW(256)没问题(256只是0-255范围之外的一个例子,我不知道unicode char 256后面是哪个符号)
Basically, Chr(13) and ChrW(13) are equal.
But ChrW accepts unicode characters, and Chr only ANSI and converts any integer value from 0 to 255 using the current code page to a Char
more information on msdn: Chr, ChrW Functions
Chr(256) is not allowed, but ChrW(256) is OK (256 is only an example outside range 0-255, I do not know which symbol is behind the unicode char 256)
Chr的有效范围是0到255,
和
ChrW的有效范围是-32768到65535.
Chr(13)=回车 - (移动光标到最左边)
Microsoft.VisualBasic.ChrW(13)是enter
The valid range for Chr is 0 through 255,
and
the valid range for ChrW is -32768 through 65535.
Chr(13) = Carriage Return - (moves cursor to lefttmost side)
Microsoft.VisualBasic.ChrW(13) is "enter"
