Parameters
Returns
Type | Description |
|---|---|
| T | A reference to the object interpreted as the target type. |
Remarks
The method converts a reference of one type to another type. Use this method for direct type conversions, such as during low-level memory operations or when you interact with unmanaged code where type safety is not enforced.
AsApply caution when you use this method. Improper casts may lead to runtime exceptions or undefined behavior if the types are incompatible. This method bypasses the usual type safety checks and provides flexibility but less safety.
