Convert.ToByte Method (Object)

Silverlight

Converts the value of the specified Object to an 8-bit unsigned integer.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public static byte ToByte(
	Object value
)

Parameters

value: Type: System.Object
An Object that implements the IConvertible interface or null.

Return Value

Type: System.Byte
An 8-bit unsigned integer equivalent to the value of value, or zero if value is null.

Exceptions

Exception	Condition
InvalidCastException	value does not implement IConvertible.

Remarks

If value is not null, this method wraps a call to the IConvertible.ToByte implementation of the underlying type of value.

Examples

The following code sample illustrates the use of ToByte, converting a String value to a Byte :


public void ConvertStringByte(string stringVal)
{
   byte byteVal = 0;

   try
   {
      byteVal = System.Convert.ToByte(stringVal);
      outputBlock.Text += String.Format("{0} as a byte is: {1}",
         stringVal, byteVal) + "\n";
   }
   catch (System.OverflowException)
   {
      outputBlock.Text += String.Format(
         "Conversion from string to byte overflowed.") + "\n";
   }
   catch (System.FormatException)
   {
      outputBlock.Text += String.Format(
         "The string is not formatted as a byte.") + "\n";
   }
   catch (System.ArgumentNullException)
   {
      outputBlock.Text += String.Format(
         "The string is null.") + "\n";
   }

   //The conversion from byte to string is always valid.
   stringVal = System.Convert.ToString(byteVal);
   outputBlock.Text += String.Format("{0} as a string is {1}",
      byteVal, stringVal) + "\n";
}
