The following table summarizes all the data type convert options.
| Task | Functions | Examples |
|---|---|---|
| Parsing base 10 numbers | Parse TryParse | double d = double.Parse ("3.5"); int i; bool ok = int.TryParse ("3", out i); |
| Parsing from base 2, 8, or 16 | Convert.ToIntegral | int i = Convert.ToInt32 ("1E", 16); |
| Formatting to hexadecimal | ToString ("X") | string hex = 45.ToString ("X"); |
| Lossless numeric conversion | Implicit cast | int i = 23; double d = i; |
| Truncating numeric conversion | Explicit cast | double d = 23.5; int i = (int) d; |
| Rounding numeric conversion (real to integral) | Convert.ToIntegral | double d = 23.5; int i = Convert.ToInt32 (d); |
