    LiveMin<TSource>(View<TSource>,Expression<Func<TSource,Int32>>) Method
    In This Topic
    Computes the minimum value of a view of System.Int32 values that are obtained by invoking a transform function on each element of the source view.

    Parameters

    source
    A view containing the values to determine the minimum value of.
    selector
    A transform function to apply to each element.

    Type Parameters

    TSource
    The type of the elements of source.

    Return Value

    A view representing the minimum of the values.
    Remarks

    If the source is empty, an System.InvalidOperationException is thrown.

    It is possible to use standard LINQ query operator Min instead of LiveMin. Both are "live" in the sense that they are recomputed automatically when any change occurs in the source. The difference is that Min will every time loop through the entire source collection and aggregate it from scratch, whereas LiveMin will use a more performant algorithm, will maintain its value incrementally, processing only those source items that actually changed.
