Console.WriteLine（s）是否缺少线路终结器？ [英] Console.WriteLine(s) Is Missing Line Terminator?

问题描述

大家好，


我有一个简单的VB代码：


Sub OutputLine（ByRef Level As String，ByRef InfoString As String）

Const gSTDOUT As Integer = -11

Dim hStdOut，BytesWritten As Integer

Dim s As String


s =等级& " " &安培; InfoString

Console.WriteLine（s）

End Sub


这应该将字符串s写入标准输出每行返回

时间。但是，我在这里有两个问题：


1）输出中缺少级别 - 它只包含InfoString。对于

实例：当Level =" INFO"和InforString =" Process started"时，

输出为Process started。只有;

2）最后没有换行符。


关于它发生了什么以及如何解决这个问题的建议？谢谢！

您是否可以发布一个小型的完整应用程序，让我们重现您所看到的行为？b
Console.WriteLine在这里一直很好用

所以我怀疑你的输入不正确。

另外，根据经验，避免使用''&''来连接字符串，因为它有隐藏投射错误的b $ ba倾向。它只适用于那里的VB6风格

兼容性，并且应该与选项明确一起烧掉赌注

关闭:)


尝试在Console.WriteLine语句上放置一个断点，看看变量'''''包含什么
。也许你在

结束时传递控制角色？


干杯，

嗯？你能举个例子吗？那么你建议我们使用

代替？希望不是+运算符。

>它只适用于VB6风格的兼容性，

不，它肯定不是。

Hi All,

I have a simple VB code:

Sub OutputLine(ByRef Level As String, ByRef InfoString As String)
Const gSTDOUT As Integer = -11
Dim hStdOut, BytesWritten As Integer
Dim s As String

s = Level & " " & InfoString
Console.WriteLine(s)

End Sub

This should write string s to a standard output with a line return each
time. However, I have two issues here:

1) Level is missing from the output - It only contains InfoString. For
instance: When Level = "INFO", and InforString = "Process started", The
output is "Process started" only;
2) No newline character at the end.

Any advice on what it going on and how to get this resolved? Thanks!

Can you post a small complete application that will let us reproduce
the behaviour you''re seeing? Console.WriteLine has always worked fine
here so I suspect your input is incorrect.

Also as a rule of thumb, avoid using ''&'' to concatenate strings, as it has
a tendency to hide casting errors. It''s only in there for VB6 style
compatibility, and should be burned at the stake along with Option Explicit
Off :)

Try placing a breakpoint on the Console.WriteLine statement and see what
the variable ''s'' contains. Perhaps you''re passing control characters on the
end?

Huh? Can you give an example of that? And what do you suggest we use
instead? Hopefully not the + operator.

>It''s only in there for VB6 style compatibility,

No it certainly isn''t.
