myTimeSpan.ToString(@"hh\:mm")
Custom TimeSpan Format Strings
The custom TimeSpan format specifiers do not include placeholder separator symbols, such as the symbols that separate days from hours, hours from minutes, or seconds from fractional seconds. Instead, these symbols must be included in the custom format string as string literals. For example, "dd.hh\:mm" defines a period (.) as the separator between days and hours, and a colon (:) as the separator between hours and minutes.
自定义 TimeSpan 格式说明符不包括占位符分隔符，例如将天与小时、小时与分钟或秒与小数秒分开的符号。相反，这些符号必须作为字符串文字包含在自定义格式字符串中。例如，“dd.hh\:mm”将句点 (.) 定义为天和小时之间的分隔符，将冒号 (:) 定义为小时和分钟之间的分隔符。

From TimeSpan.ToString Method (String)
从 TimeSpan.ToString Method (String)
TimeSpan t = new TimeSpan(14, 53, 0);
Console.WriteLine(t.ToString(@"hh\:mm"));
As an alternative you can use String.Formatlike;
作为替代，您可以使用String.Formatlike；
Console.WriteLine(String.Format("{0}:{1}", t.Hours, t.Minutes));
Remember, TimeSpan.ToString(String)overload only avaiable for .NET 4 or higher.
请记住，TimeSpan.ToString(String)重载仅适用于 .NET 4 或更高版本。
