I have a piece of code where a need to look for specific patterns in a
string. Because there are over 20 patterns I want to place these in a string
array for quick access
if(myValue.Inde xOf(myArray)!=-1)
{
//Replace this pattern with a value from another array
}
I tried doing this in a 2 dim array, where one dimension was the pattern and
the other was the replace value. But using FOREACH(string s in myArray) I
couldn’t get it to iterate though the collection.
However I see indexof only accept char arrays. How can I better accomplish
this without a ton of IF statements

It's not entirely clear to me what you're after.
Could you post a short but complete program which demonstrates the
problem?

If I understand you correctly:
string[,] testValues = new string[,] { {"HUGE", "BIG"}, {"UGLY", "BAD"} };
for (int i = 0 i < testValues.GetL enth(0); i++)
{
if myValue.IndexOf (testValues[i][0] > -1)
// do something with textValues[i][1]
}

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
