Console.CursorTop Property
Assembly: mscorlib (in mscorlib.dll)
| Exception type | Condition |
|---|---|
| The value in a set operation is less than zero. -or- The value in a set operation is greater than or equal to BufferHeight. | |
| The user does not have permission to perform this action. | |
| An I/O error occurred. |
This example demonstrates the CursorLeft and CursorTop properties, and the SetCursorPosition and Clear methods. The example positions the cursor, which determines where the next write will occur, to draw a 5 character by 5 character rectangle using a combination of "+", "|", and "-" strings. Note that the rectangle could be drawn with fewer steps using a combination of other strings.
