StringBuilderExtensions

Extension methods for StringBuilder.

internal static class StringBuilderExtensions

Examples

The following example shows how to use Append and AppendLine with spans.

using System;
using System.Text;
using Hertzole.SourceGen;

public static class Joiner
{
    public static string Join(ReadOnlySpan<char> a, ReadOnlySpan<char> b)
    {
        StringBuilder builder = new StringBuilder();

        builder.Append(a);
        builder.Append(", ");
        builder.AppendLine(b);

        return builder.ToString();
    }
}

Methods

Append(StringBuilder, ReadOnlySpan<char>)

Appends the string representation of a specified read-only character span to this instance.

public static StringBuilder Append(this StringBuilder builder, ReadOnlySpan<char> value);

`builder`

The StringBuilder instance to append to.

`value`

The read-only character span to append.

Remarks

If the project allows unsafe code, this method uses a pointer to the span instead of appending each character in the span, thus being faster. It is recommended to enable unsafe code.

Returns

A reference to this instance after the append operation is completed.

AppendLine(StringBuilder, ReadOnlySpan<char>)

Appends the string representation of a specified read-only character span followed by the default line terminator to the end of the current StringBuilder object

public static StringBuilder AppendLine(this StringBuilder builder, ReadOnlySpan<char> value);
