Is there a C# type for representing an integer Range?

I found it best to roll my own. Some people use Tuples or Points, but in the end you want your Range to be extensive and provide some handy methods that relate to a Range. It’s also best if generic (what if you need a range of Doubles, or a range of some custom class?) For example:

/// <summary>The Range class.</summary>
/// <typeparam name="T">Generic parameter.</typeparam>
public class Range<T> where T : IComparable<T>
{
    /// <summary>Minimum value of the range.</summary>
    public T Minimum { get; set; }

    /// <summary>Maximum value of the range.</summary>
    public T Maximum { get; set; }

    /// <summary>Presents the Range in readable format.</summary>
    /// <returns>String representation of the Range</returns>
    public override string ToString()
    {
        return string.Format("[{0} - {1}]", this.Minimum, this.Maximum);
    }

    /// <summary>Determines if the range is valid.</summary>
    /// <returns>True if range is valid, else false</returns>
    public bool IsValid()
    {
        return this.Minimum.CompareTo(this.Maximum) <= 0;
    }

    /// <summary>Determines if the provided value is inside the range.</summary>
    /// <param name="value">The value to test</param>
    /// <returns>True if the value is inside Range, else false</returns>
    public bool ContainsValue(T value)
    {
        return (this.Minimum.CompareTo(value) <= 0) && (value.CompareTo(this.Maximum) <= 0);
    }

    /// <summary>Determines if this Range is inside the bounds of another range.</summary>
    /// <param name="Range">The parent range to test on</param>
    /// <returns>True if range is inclusive, else false</returns>
    public bool IsInsideRange(Range<T> range)
    {
        return this.IsValid() && range.IsValid() && range.ContainsValue(this.Minimum) && range.ContainsValue(this.Maximum);
    }

    /// <summary>Determines if another range is inside the bounds of this range.</summary>
    /// <param name="Range">The child range to test</param>
    /// <returns>True if range is inside, else false</returns>
    public bool ContainsRange(Range<T> range)
    {
        return this.IsValid() && range.IsValid() && this.ContainsValue(range.Minimum) && this.ContainsValue(range.Maximum);
    }
}
