window forms - finding record error
Hi evreyone !
While trying to find a record in a dataset by the key with the following code:
object[] key = new object[4];
key[0]=x;
key[1]=y;
key[2]=Q;
key[3]=z;
DataRow row = dataset1.tablename.Rows.find(key);
I got the error message:
An unhandled exception of type 'System.ArgumentException' occurred in system.data.dll
Additional information: Expecting 2 value(s) for the key being indexed, but received 4 value(s).
I don't understand the meening of it because my table in the sqlServerDB has 4 column key.
Does someone has a clue ???
