StringBuilder, add Tab between Values
提问by eMi
I have a small problem:
我有一个小问题：
I have a List of fields, with 3 Values. I want to build my String with these three Values, delimited by a "TAB"..
我有一个字段列表，有 3 个值。我想用这三个值构建我的字符串，用“TAB”分隔。
Code:
代码：
StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
stringBuilder.Append(field).Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();
The Tab is only between the 3rd and 2nd Value (Between 1st and 2nd is a Space ?!)
选项卡仅在第 3 个和第 2 个值之间（第 1 个和第 2 个值之间是空格？！）
So I tried this:
所以我试过这个：
StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
stringBuilder.Append(field + "\t").Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();
Then I have 2 Tabs between 3rd and 2nd, one Tab between 1st and 2nd and also a Space between 1st and 2nd..
然后我在第 3 个和第 2 个之间有 2 个标签，第 1 个和第 2 个之间有一个标签，第 1 个和第 2 个之间还有一个空格。
(The Space is always there, how to avoid that?)
（空间总是在那里，如何避免？）
So what I have to do? Need only(without spaces..) a Tab between these Values..
那我该怎么办？只需要（没有空格..）这些值之间的制表符..

try
尝试
StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
stringBuilder.Append(field.Trim()).Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();
Basically I would just use return string.Join ( "\t", fields );.
基本上我只会使用return string.Join ( "\t", fields );.

I would have thought you would want
我以为你会想要
StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
stringBuilder.Append(field);
stringBuilder.Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

Instead of looping, you can use string.Join:
您可以使用string.Join：
StringBuilder stringBuilder = new StringBuilder();
stringBuilder.AppendLine(string.Join("\t", fields));
Note that you can pass in the string directly to AppendLineas well.
请注意，您也可以直接将字符串传递给AppendLine。

I think you are confusing with tab char and sapces.
我认为您对 tab char 和 sapces 感到困惑。
Are you expecting fixed no of white spaces to be added in the end of every word?
您是否希望在每个单词的末尾添加固定的空格？
\t -> is just a tab char
\t -> 只是一个制表符

The above two lines have same tab char b/w the 1st & 2nd Word.
上面两行的第一个和第二个字具有相同的制表符。
if you type one more char in the end of "Javasun" it will extend like the following
如果在“Javasun”的末尾再输入一个字符，它将像下面这样扩展
