You create an application by using the Microsoft .NET Framework 3.5 and Microsoft
ADO.NET.You write the following code segment.
DataTable dt = new DataTable(“Strings”);
dt = new DataTable();
dt.Columns.Add(“Strings”);
dt.Rows.Add(“A-B”);
dt.Rows.Add(“C-D”);
var c = from Strings in dt.AsEnumerable()
select Strings[0];
int count = 0;
You need to ensure that the value of the count variable is 4. Which line of code should you add?
A.
count = c.Select(str => ((string)str).Split(‘-‘)).Count();
B.
count = c.SelectMany(str => ((string)str).Split(‘-‘)).Count();
C.
count = c.Select(str => ((string)str).Replace(‘-‘, ‘\n’)).Count();
D.
count = c.SelectMany(str => ((string)str).Replace(‘-‘,’\n’)).Count();
