- value
- A pointer to an array of Unicode characters.
- startIndex
- The starting position within value.
- length
- The number of characters within value to use.
| Exception Type |
Condition |
| ArgumentOutOfRangeException |
startIndex or length is less than zero.
-or-
value is a null pointer and length is not zero.
|
If length is zero, an Empty instance is initialized.
This constructor copies Unicode characters from value, starting at startIndex and ending at ( startIndex + length- 1 ).
If the specified range is outside of the memory allocated for the sequence of characters, the behavior of this constructor is system dependent. For example, such a situation might cause an access violation.
In C#, this constructor is defined only in the context of unmanaged code.
