F#View Source Request Example

static member ValueOrStringEmpty : 
        propertyValue : string -> string

Parameters

propertyValue String: The property value string to check

Return Value

String
The property value if not null or String.Empty if the value is null

Remarks

This may be useful if you would prefer not to have to always check for null values in string-type properties before using a string method that may throw an exception if it is null (i.e. Length).

Example

C#

string country = BaseProperty.ValueOrStringEmpty(vCard.Address.Country);

// No need to check for null first
if(country.Length != 0)
    // ... Do something with the country value ...

VB

Dim country As String = BaseProperty.ValueOrStringEmpty(vCard.Address.Country)

' No need to check for null first
If country.Length <> 0 Then
    ' ... Do something with the country value ...
End If
