我将使用 Environment.NewLine 属性

例如:

StringBuilder sb = new StringBuilder();
sb.AppendFormat("Foo{0}Bar", Environment.NewLine);
string s = sb.ToString();

或者

StringBuilder sb = new StringBuilder();
sb.Append("Foo");
sb.Append("Foo2");
sb.Append(Environment.NewLine);
sb.Append("Bar");
string s = sb.ToString();

如果您希望在每次追加后有一个新行,您可以查看 本·沃伊特的回答

I would make use of the Environment.NewLine property.

Something like:

StringBuilder sb = new StringBuilder();
sb.AppendFormat("Foo{0}Bar", Environment.NewLine);
string s = sb.ToString();

Or

StringBuilder sb = new StringBuilder();
sb.Append("Foo");
sb.Append("Foo2");
sb.Append(Environment.NewLine);
sb.Append("Bar");
string s = sb.ToString();

If you wish to have a new line after each append, you can have a look at Ben Voigt's answer.

另外,使用 StringBuilder.AppendLine 方法。

Also, using the StringBuilder.AppendLine method.

使用 StringBuilder 的追加行内置函数:

StringBuilder sb = new StringBuilder();
sb.AppendLine("First line");
sb.AppendLine("Second line");
sb.AppendLine("Third line");

输出

First line
Second line
Third line

Use StringBuilder's append line built-in functions:

StringBuilder sb = new StringBuilder();
sb.AppendLine("First line");
sb.AppendLine("Second line");
sb.AppendLine("Third line");

Output

First line
Second line
Third line

在 Linux 中它将附加 \n 而不是 \r\n

It will append \n in Linux instead \r\n.

StringBuilder sb = new StringBuilder();

您可以使用sb.AppendLine()sb.Append(Environment.NewLine)

StringBuilder sb = new StringBuilder();

You can use sb.AppendLine() or sb.Append(Environment.NewLine);

对于多行,我发现最好的方法是这样做:

        IEnumerable<string> lines = new List<string>
        {
            string.Format("{{ line with formatting... {0} }}", id),
            "line 2",
            "line 3"
        };
        StringBuilder sb = new StringBuilder();
        foreach(var line in lines)
            sb.AppendLine(line);

这样,您就不必多次重复使用 Environment.NewLine 或 AppendLine() 来使屏幕变得混乱。与必须记住键入它们相比,它也更不容易出错。

For multiple lines the best way I find is to do this:

        IEnumerable<string> lines = new List<string>
        {
            string.Format("{{ line with formatting... {0} }}", id),
            "line 2",
            "line 3"
        };
        StringBuilder sb = new StringBuilder();
        foreach(var line in lines)
            sb.AppendLine(line);

In this way you don't have to clutter the screen with the Environment.NewLine or AppendLine() repeated multiple times. It will also be less error prone than having to remember to type them.

只需为 StringBuilder 类创建一个扩展:

Public Module Extensions
    <Extension()>
    Public Sub AppendFormatWithNewLine(ByRef sb As System.Text.StringBuilder, ByVal format As String, ParamArray values() As Object)
        sb.AppendLine(String.Format(format, values))
    End Sub
End Module

Just create an extension for the StringBuilder class:

Public Module Extensions
    <Extension()>
    Public Sub AppendFormatWithNewLine(ByRef sb As System.Text.StringBuilder, ByVal format As String, ParamArray values() As Object)
        sb.AppendLine(String.Format(format, values))
    End Sub
End Module
