I have the following code:
[DisplayName("Created")]
[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}")]
public DateTime? Created { get; set; }
[DisplayName("Modified By")]
public string ModifiedBy { get; set; }
[DisplayName("Modified")]
[DisplayFormat(DataFormatString = "{0:dd/MM/yyyy}")]
public DateTime? Modified { get; set; }
from d in data
select new Content.Grid
{
PartitionKey = d.PartitionKey,
RowKey = d.RowKey,
Order = d.Order,
Title = d.Title,e
Created = d.Created,
CreatedBy = d.CreatedBy,
Modified = d.Modified,
ModifiedBy = d.ModifiedBy
};
There is a possibility that d.Created
, d.CreatedBy
, d.Modified
and d.ModifiedBy
may be null.
How can I make it so that if they are null then the select returns n/a
for the CreatedBy
and ModifiedBy
and returns the date January, 1, 2012
for the Created
and Modified
?
You can use the null-coalescing operator ( ??
) to give default values for nullable value types or reference types:
from d in data
select new Content.Grid
{
PartitionKey = d.PartitionKey,
RowKey = d.RowKey,
Order = d.Order,
Title = d.Title,e
Created = d.Created ?? new DateTime(2012,1,1),
CreatedBy = d.CreatedBy ?? "n/a",
Modified = d.Modified ?? new DateTime(2012,1,1),
ModifiedBy = d.ModifiedBy ?? "n/a"
};
