C#查詢表達式語法

VB查詢表達式語法

Skip

跳過一些指定的序列中一些的元素，並返回其餘的

不適用

Skip

SkipWhile

相同，唯一的例外跳到多個元素，跳過的是由一個布爾條件指定

不適用

Skip While

Take

採取元素指定數量的序列，並跳過其餘的

Take

TakeWhile

相同，以不同的事實，即許多元素採取的是由一個布爾條件指定

Skip例子- 查詢表達式

VB

Module Module1 Sub Main() Dim words = {"once", "upon", "a", "time", "there", "was", "a", "jungle"} Dim query = From word In words Skip 4 Dim sb As New System.Text.StringBuilder() For Each str As String In query
sb.AppendLine(str) Console.WriteLine(str) Next Console.ReadLine() End Sub End Module

當在VB上述代碼被編譯和執行時，它產生了以下結果：

there
was
a
jungle

Skip While示例 - 查詢表達式

VB

Module Module1 Sub Main() Dim words = {"once", "upon", "a", "time", "there", "was", "a", "jungle"} Dim query = From word In words Skip While word.Substring(0, 1) = "t" Dim sb As New System.Text.StringBuilder() For Each str As String In query
sb.AppendLine(str) Console.WriteLine(str) Next Console.ReadLine() End Sub End Module

當在VB上述代碼被編譯和執行時，它產生了以下結果：

once
upon
a
was
a
jungle

Take例子- 查詢表達式

VB

Module Module1 Sub Main() Dim words = {"once", "upon", "a", "time", "there", "was", "a", "jungle"} Dim query = From word In words Take 3 Dim sb As New System.Text.StringBuilder() For Each str As String In query
sb.AppendLine(str) Console.WriteLine(str) Next Console.ReadLine() End Sub End Module

當在VB上述代碼被編譯和執行時，它產生了以下結果：

once
upon
a

Take While示例 - 查詢表達式

VB

Module Module1 Sub Main() Dim words = {"once", "upon", "a", "time", "there", "was", "a", "jungle"} Dim query = From word In words Take While word.Length < 6 Dim sb As New System.Text.StringBuilder() For Each str As String In query
sb.AppendLine(str) Console.WriteLine(str) Next Console.ReadLine() End Sub End Module

當在VB上述代碼被編譯和執行時，它產生了以下結果：

once
upon
a
time
there
was
a
