Do you initialize variables outside of the try block?
Last updated by Brady Stroud [SSW] 7 months ago.See historyYou should initialize variables outside of the try block.
Cursor cur;
try {
// ...
cur = Cursor.Current; //Bad Code - initializing the variable inside the try block
Cursor.Current = Cursors.WaitCursor;
// ...
} finally {
Cursor.Current = cur;
}Bad Example: Because of the initializing code inside the try block. If it failed on this line then you will get a NullReferenceException in Finally
Cursor cur = Cursor.Current; //Good Code - initializing the variable outside the try block
try {
// ...
Cursor.Current = Cursors.WaitCursor;
// ...
} finally {
Cursor.Current = cur;
}Good Example : Because the initializing code is outside the try block
