Use the TryParse static methods of all of the following types:

• Byte
• SByte
• Int16
• UInt16
• Int32
• UInt32
• Int64
• UInt64
• Single
• Double

For characters, you will have to be more specific — do you want the input converted by character (e.g. if they enter 5 the character value will be 53, the ASCII value representing the digit 5), or by value (e.g. they would have to enter 53 to produce the digit 5)?
