StringBuilder的，值之间添加标签 [英] StringBuilder, add Tab between Values

问题描述

我有一个小问题：

我有字段列表，具有3个值。我想建立我的字符串，这三个值，
通过一个分隔的TAB ..

I have a List of fields, with 3 Values. I want to build my String with these three Values, delimited by a "TAB"..

code：

StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
    stringBuilder.Append(field).Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

标签仅仅是第3和第2个数值之间（第一和第二之间是一个空间？！）

The Tab is only between the 3rd and 2nd Value (Between 1st and 2nd is a Space ?!)

所以，我想这样的：

StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
    stringBuilder.Append(field + "\t").Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

然后，我有第三和第二之间2标签，第一和第二，也是一个空间之间的一个标签
第一和第二之间的..

Then I have 2 Tabs between 3rd and 2nd, one Tab between 1st and 2nd and also a Space between 1st and 2nd..

（空间总是存在的，如何避免？）

(The Space is always there, how to avoid that?)

所以我有什么关系？需要的仅（无空格。）这些值之间的标签。

So what I have to do? Need only (without spaces..) a Tab between these Values..

推荐答案

尝试

StringBuilder stringBuilder = new StringBuilder();
foreach (string field in fields)
{
    stringBuilder.Append(field.Trim()).Append("\t");
}
stringBuilder.AppendLine();
return stringBuilder.ToString();

基本上，我只想用 返回的string.join（\\ t的，域）;
