[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Indicates whether the regular expression specified in the Regex constructor finds a match in a specified input string.

Namespace:  System.Text.RegularExpressions
Assembly:  System.Text.RegularExpressions (in System.Text.RegularExpressions.dll)

Syntax

'Declaration
Public Function IsMatch ( _
    search As String _
) As Boolean

public bool IsMatch(
    string search
)

public:
bool IsMatch(
    String^ search
)

member IsMatch : 
        search:string -> bool 

public function IsMatch(
    search : String
) : boolean

Parameters

• search
  Type: System. . :: . .String
  The string to search for a match.

Return Value

Type: System. . :: . .Boolean
true if the regular expression finds a match; otherwise, false.

Remarks

The IsMatch method is typically used to validate a string or to ensure that a string conforms to a particular pattern without retrieving that string for subsequent manipulation. If you want to determine whether one or more strings match a regular expression pattern and then retrieve them for subsequent manipulation, call the Match or Matches method.
