May be the questions look simple or may be the solution is also simple.But i have tried lot,But cant make this possible, I have a string[] array which has a value="".And i want to check this in an if condition
if (del.counts==null && del.mrate==null)
{
///
}
I have tried IsNullorEmpty,equal..etc but nothing gives me the solution

You want to use array indexing if you know where in the array the element is that you want to check. So like this in your case:
if (string.IsNullOrEmpty(del.counts[0]))
{
// Code
}
If you do not know where the element is you'll want to use Linq's Any(...) extension Mehtod.
if (del.counts.Any(value => string.IsNullOrEmpty(value))
{
// Code
}
Any(...) will return true if any element of the array is NullOrEmpty and false if not
So you would use it like so in your application:
if (del.counts == null && del.mrate == null)
{
// Your code to handle if 'del.counts' and 'del.mrate' are null
}
// We know 'del.counts' is not null, but one of the elements may be NullOrEmpty
else if (del.counts.Any(value => string.IsNullOrEmpty(value)))
{
// Your code to handle if one of the counts elements IsNullOrEmpty
}
You may want to remove the else if and replace it with an if statement depending on your context
string.IsNullOrEmpty(del.counts[0])? Note that it is notdel.countswhich has the value"". It is the first element inside it:del.counts[0]
