Error Message
Cannot apply indexing with [] to an expression of type 'type'

i hawe variable that i use in FOR LOOP, like this;

Int32 tempFor1 = pozicije.GetUpperBound(0);
for (i = 0; i <= tempFor1; i++)
{
myAdd = Convert.ToInt32(myPozition);
oCmd.Parameters["@advId"].Value = myAdd;
oCmd.Parameters["@pozition"].Value = i;

What the error is saying that the type of oCmd.Parameters does not have an indexer on it. They usually look something like this in code:

public int this [int index] // Indexer declaration
{
get
{
// Check the index limits.
if (index < 0 || index >= 100)
return 0;
else
return myArray[index];
}
set
{
if (!(index < 0 || index >= 100))
myArray[index] = value;
}
}

So, look at the datatype for the Parameters property on your oCmd object and see if it has an indexer.
