Methods

JoinAsString(IEnumerable<string>, string)

Concatenates the members of a constructed IEnumerable<T> collection of type System.String, using the specified separator between each member. This is a shortcut for string.Join(...)

public static string JoinAsString(this IEnumerable<string> source, string separator)

Parameters

source IEnumerable<string>

A collection that contains the strings to concatenate.

separator string

The string to use as a separator. separator is included in the returned string only if values has more than one element.

Returns

string

A string that consists of the members of values delimited by the separator string. If values has no members, the method returns System.String.Empty.

JoinAsString<T>(IEnumerable<T>, string)

Concatenates the members of a collection, using the specified separator between each member. This is a shortcut for string.Join(...)

public static string JoinAsString<T>(this IEnumerable<T> source, string separator)

Parameters

source IEnumerable<T>

A collection that contains the objects to concatenate.

separator string

The string to use as a separator. separator is included in the returned string only if values has more than one element.

Returns

string

A string that consists of the members of values delimited by the separator string. If values has no members, the method returns System.String.Empty.

Type Parameters

T

The type of the members of values.

WhereIf<T>(IEnumerable<T>, bool, Func<T, bool>)

Filters a IEnumerable<T> by given predicate if given condition is true.

public static IEnumerable<T> WhereIf<T>(this IEnumerable<T> source, bool condition, Func<T, bool> predicate)

Parameters

source IEnumerable<T>

Enumerable to apply filtering

condition bool

A boolean value

predicate Func<T, bool>

Predicate to filter the enumerable

Returns

IEnumerable<T>

Filtered or not filtered enumerable based on condition

Type Parameters

T

WhereIf<T>(IEnumerable<T>, bool, Func<T, int, bool>)

Parameters

source IEnumerable<T>

Enumerable to apply filtering

condition bool

A boolean value

predicate Func<T, int, bool>

Predicate to filter the enumerable

Returns

IEnumerable<T>

Filtered or not filtered enumerable based on condition

Type Parameters
