Remarks
You use the DataType enumeration when you apply the DataTypeAttribute attribute to a property. The DataType enumeration contains valid values you use with the DataTypeAttribute attribute. You use the DataTypeAttribute attribute to specify the type of data that is expected for the property beyond the data type of the property. For example, properties named Phone and EmailAddress may both contain string values, but you can specify the expected values by applying the DataTypeAttribute attribute with the PhoneNumber and EmailAddress values respectively.
Examples
The following example shows how to specify an e-mail address property and a phone number property.
Public Class Customer
<DataType(DataType.EmailAddress)> _
Public Property EmailAddress As String
'Implement Get and Set logic
End Property
<DataType(DataType.PhoneNumber)> _
Public Property Phone As String
'Implement Get and Set logic
End Property
End Class
public class Customer
{
[DataType(DataType.EmailAddress)]
public string EmailAddress { get; set; }
[DataType(DataType.PhoneNumber)]
public string Phone { get; set; }
}
