c# - 用等效字符串表示 Char

Question

我有以下类作为 ListBox 的 DataSource:

class SeparatorChars
{
    /// <summary>
    /// Text to describe character
    /// </summary>
    public string Text { get; set; }

    /// <summary>
    /// Char value of the character
    /// </summary>
    public char Value { get; set; }

    /// <summary>
    /// Represent object as string
    /// </summary>
    /// <returns>String representing object</returns>
    public override string ToString()
    {
        return Text + " '" + Value + "'";
    }
}

问题是，默认情况下，这将使用 Value 作为添加到字符串的常规字符，例如，如果我为 Tab 定义此类，如下所示:

var TabSeparator = new SeparatorChars {Text = "Tab", Value = '\t'}

字符串表示将是:

Tab '     '

但我需要它

Tab '\t'

如何做到这一点？!

无可否认，大部分内容来自 this post未经测试。

public override string ToString()
{
    return ToLiteral(Text + " '" + Value + "'");
}

private string ToLiteral(string input)
{
    var writer = new StringWriter();
    CSharpCodeProvider provider = new CSharpCodeProvider();
    provider.GenerateCodeFromExpression(new CodePrimitiveExpression(input), writer, null);
    return writer.ToString();
}
