StringValidatorAttribute Constructor

Initializes a new instance of the StringValidatorAttribute class.

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

public StringValidatorAttribute()

You use this constructor in the attributed model to ensure that the value assigned to the configuration-element property is of a string type.

The following example shows how to use the StringValidatorAttribute constructor.

[ConfigurationProperty("alias", DefaultValue = "anotherName.txt",
    IsRequired = true, IsKey = false)]
[StringValidator()]
public string Alias
{
    get
    {
        return (string)this["alias"];
    }
    set
    {
        this["alias"] = value;
    }
}
