Deleting Element of An Array in c# without using lambda expression

Question

.NET3.5

suppose i have an array like

string[] test={"1","","2","","3"};

i want to remove it so the answer is like

test={"1","2","3"}

but without using lambda expression like

test =  test.Where(x => !string.IsNullOrEmpty(x)).ToArray();

How to achieve this?

Thanks in advance

Note : Cannot use lambda expression because it blocks changes at time of debugging

C#

string[] test = { "1", "", "2", "", "3" };
test = test.Except(new List<string> { string.Empty }).ToArray();

Solution 1

Hi,
You can use foreach loop instead of lamda expression.

C#

string[] test1;
int j=0;
foreach(item i in test)
{
if(!string.IsNullOrEmpty(i))
{
j=j+1;
test1[j] = i
}
}

I have not tested code but you can do something like this.

Hi,
see final result you want as an array with not null and empty records. Now if you delete element from an array using forloop, so it will give error as you can't change collection runtime.
So I suggested another array which will store your required result.
