Newline character in StringBuilder

问题

How do you append a new line(\n\r) character in StringBuilder?

回答1:

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();

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.

回答2:

With the AppendLine method.

回答3:

Also, using the StringBuilder.AppendLine method.

回答4:

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

回答5:

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

回答6:

StringBuilder sb = new StringBuilder();

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

回答7:

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.

回答8:

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
