The example below illustrates how to implement String Properties in an Entity Framework Code-First class.

C#

// By default, the string property size is 100.
public string DefaultSizeStringProperty { get; set; }
// The string property size is limited to 15.
[FieldSize(15)]
string ShortSizeStringProperty { get; set; }
// The string property size is unlimited. It is displayed via a memo editor.
// By default, this property is not displayed in List View. You can make its column visible via the VisibleInListView attribute.
[FieldSize(FieldSizeAttribute.Unlimited), VisibleInListView(true)]
public string UnlimitedSizeStringProperty { get; set; }
// The property has a list of predefined values.
[ModelDefault("PredefinedValues",
    "Predefined Value 1;Predefined Value 2;Predefined Value 3;Predefined Value 4;Predefined Value 5")]
public string StringWithPredefinedValuesProperty { get; set; }

VB.NET

' By default, the string property size is 100.
Public Property DefaultSizeStringProperty() As String
' The string property size is limited to 15.
<FieldSize(15)>
Private Property ShortSizeStringProperty() As String
' The string property size is unlimited. It is displayed via a memo editor.
' By default, this property is not displayed in List View. You can make its column visible via the VisibleInListView attribute.
<FieldSize(FieldSizeAttribute.Unlimited), VisibleInListView(True)>
Public Property UnlimitedSizeStringProperty() As String
' The property has a list of predefined values.
<ModelDefault("PredefinedValues", _
"Predefined Value 1;Predefined Value 2;Predefined Value 3;Predefined Value 4;Predefined Value 5")>
Public Property StringWithPredefinedValuesProperty() As String
