Отметьте это, он поддерживает форматирование:
public static string StringFormat(string format, IDictionary<string, object> values)
{
var matches = Regex.Matches(format, @"\{(.+?)\}");
List<string> words = (from Match matche in matches select matche.Groups[1].Value).ToList();
return words.Aggregate(
format,
(current, key) =>
{
int colonIndex = key.IndexOf(':');
return current.Replace(
"{" + key + "}",
colonIndex > 0
? string.Format("{0:" + key.Substring(colonIndex + 1) + "}", values[key.Substring(0, colonIndex)])
: values[key].ToString());
});
}
Как использовать:
string format = "{foo} is a {bar} is a {baz} is a {qux:#.#} is a really big {fizzle}";
var dictionary = new Dictionary<string, object>
{
{ "foo", 123 },
{ "bar", true },
{ "baz", "this is a test" },
{ "qux", 123.45 },
{ "fizzle", DateTime.Now }
};
StringFormat(format, dictionary)
