VB.Net provides a wide range of data types. The following table shows all the data types available:
| Data Type | Storage Allocation | Value Range |
|---|---|---|
| Boolean | Depends on implementing platform | True or False |
| Byte | 1 byte | 0 through 255 (unsigned) |
| Char | 2 bytes | 0 through 65535 (unsigned) |
| Date | 8 bytes | 0:00:00 (midnight) on January 1, 0001 through 11:59:59 PM on December 31, 9999 |
| Decimal | 16 bytes | 0 through +/-79,228,162,514,264,337,593,543,950,335 (+/-7.9...E+28)with no decimal point; 0 through +/-7.9228162514264337593543950335 with 28 places to the right of the decimal |
| Double | 8 bytes | -1.79769313486231570E+308 through -4.94065645841246544E-324, for negative values
4.94065645841246544E-324 through 1.79769313486231570E+308, for positive values

| Object | 4 bytes on 32-bit platform
8 bytes on 64-bit platform
| Any type can be stored in a variable of type Object |
| SByte | 1 byte | -128 through 127 (signed) |
| Short | 2 bytes | -32,768 through 32,767 (signed) |
