Char.IsSeparator Method (Char)
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Indicates whether the specified Unicode character is categorized as a separator character.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
Public Shared Function IsSeparator ( _
c As Char _
) As Boolean
public static bool IsSeparator(
char c
)
Parameters
- c
Type: System..::.Char
A Unicode character.
Return Value
Type: System..::.Boolean
true if c is a separator character; otherwise, false.
Remarks
The Unicode standard recognizes three subcategories of separators:
Space separators (the UnicodeCategory..::.SpaceSeparator category), which includes characters such as \u0020.
Line separators (the UnicodeCategory..::.LineSeparator category), which includes \u2028.
Paragraph separators (the UnicodeCategory..::.ParagraphSeparator category), which includes \u2029.
Note
The Unicode standard classifies the characters \u000A (LF), \u000C (FF), and \u000A (CR) as control characters (members of the UnicodeCategory..::.Control category), not as separator characters.
Examples
The following example lists the Char objects that are classified as separator characters.
Module Example
Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
For ctr As Integer = Convert.ToInt32(Char.MinValue) To Convert.ToInt32(Char.MaxValue)
Dim ch As Char = ChrW(ctr)
If Char.IsSeparator(ch) Then
outputBlock.Text += String.Format("\u{0:X4} ({1})", AscW(ch), Char.GetUnicodeCategory(ch).ToString()) & vbCrLf
End If
Next
End Sub
End Module
