method IteratesALL #

IteratesALL``1(IEnumerable(Of IEnumerable(Of ``0)))

Iterates all of the elements in a two dimension collection as the data source for the linq expression or ForEach statement.

(适用于二维的集合做为linq的数据源，不像Extensions.Unlist()是进行转换，这个是返回迭代器的，推荐使用这个函数)

Remarks

this function is a safe function, the null collection value in the given source will be ignored

Type Parameters

Name	Description
`T`

Parameters

Name	Type	Description
`source`	IEnumerable(Of IEnumerable(Of ``0))	-

method JoinIterates #

JoinIterates``1(IEnumerable(Of ``0), IEnumerable(Of ``0))

First, iterate populates the elements in collection a, and then populate out all of the elements on collection b

Type Parameters

Name	Description
`T`

Parameters

Name	Type	Description
`a`	IEnumerable(Of ``0)	Object collection
`b`	IEnumerable(Of ``0)	Another object collection.

Returns

a or b will be ignored if collection object is nothing
