The answer from ChrisF is correct as far as StringBuilder.Append is concerned.
就 StringBuilder.Append 而言，ChrisF 的回答是正确的。
In general, the word "Append" means "to add to the end of". See http://en.wiktionary.org/wiki/append.

I would guess that sbis of type StringBuilder.
我猜那sb是类型StringBuilder。
Append()adds the supplied string to the end of the string being built in the StringBuildervariable.
Append()将提供的字符串添加到StringBuilder变量中正在构建的字符串的末尾。

It will add the string representation of the object to end of the string builder instance. It basically calls the .ToString() method of whatever object you pass in and concatenates it to the end of the internal string being build up.
它将对象的字符串表示添加到字符串构建器实例的末尾。它基本上调用您传入的任何对象的 .ToString() 方法，并将其连接到正在构建的内部字符串的末尾。
请参阅MSDN 文档

This is quite simple. Then code above is simply "adding" or "appending" the variables/text supplied within the brackets to the variable "sb".
这很简单。然后上面的代码只是将括号内提供的变量/文本“添加”或“附加”到变量“sb”。
Append can be found as part of the System.Text.StringBuilderclass which I believe is being used above.
Append 可以作为System.Text.StringBuilder我认为上面使用的类的一部分找到。

I would point out that the "right" way to do that bit of code is:
我要指出的是，执行那段代码的“正确”方法是：
public static void appendData(string data)
{
if (isRecording)
{
sb.Append(data);
sb.Append(Environment.NewLine);
}
}
Append is doing the same job as string1 + string2 but it is doing it in a much more efficient manner. Look up "Immutable Strings C#" for some more details if you need them.
Append 与 string1 + string2 做同样的工作，但它以更有效的方式完成。如果需要，请查阅“Immutable Strings C#”以获取更多详细信息。

Assuming you are using Visual Studio put your cursor on the word Append and Press F1, you'll probably see something like this. If you are considering refactoring this and assuming it is using a StringBuilder, you might also want to read about AppendLine.
假设您使用的是 Visual Studio，将光标放在单词 Append 上并按 F1，您可能会看到类似这样的内容。如果您正在考虑重构它并假设它使用的是 StringBuilder，您可能还想阅读AppendLine。
