Dear all, How i match 2 array and keep the matched value into a new array using c#?
for (int j = 0; j < arrayA.Length; j++)
{
for (int k = 0; k < arrayB.Length; k++)
{
if (arrayA[j] == arrayB[k])
{
arrayB[k];
//How i keep this matched record into a new array?
}
}
}
Another thing: Is their any short cut way to match 2 array and keep the record into a new array? Any kind heart. Please help.
Why don't use LINQ:
var matchingValues = arrayA.Intersect(arrayB).ToArray();
SIDE NOTE:
the resulting array will have distinct values.
Store it in a List<int> or any type you have. (I assume yours is int)
List<int> list = new List<int>();
for (int j = 0; j < arrayA.Length; j++)
{
for (int k = 0; k < arrayB.Length; k++)
{
if (arrayA[j] == arrayB[k])
{
list.Add(arrayB[k]); // HERE !!
}
}
}
Now if you need to change it to an array, you can do at the end:
int[] finalArray = list.ToArray();
