RegexStringValidatorAttribute Constructor

Note: This constructor is new in the .NET Framework version 2.0.

Initializes a new instance of the RegexStringValidatorAttribute object.

Namespace: System.Configuration
Assembly: System.Configuration (in system.configuration.dll)

public RegexStringValidatorAttribute (
	string regex
)
public RegexStringValidatorAttribute (
	String regex
)
public function RegexStringValidatorAttribute (
	regex : String
)

Parameters

regex

The string to use for regular expression validation.

The regex parameter contains the regular expression pattern that a string must match before it can be assigned to the decorated configuration-element property.

You use this constructor in the attributed model to ensure that the string value assigned to the related property contains only the allowed characters.

The following example shows how to use the RegexStringValidatorAttribute constructor.

[ConfigurationProperty("alias2", DefaultValue = "alias.txt",
    IsRequired = true, IsKey = false)]
[RegexStringValidator(@"\w+\S*")]
public string Alias2
{
    get
    {
        return (string)this["alias2"];
    
    set
    {
        this["alias2"] = value;
