)

Examples
The following code sample illustrates the conversion of a Double to a String, using ToString.
Public Sub ConvertDoubleString(ByVal doubleVal As Double)
Dim stringVal As String
' A conversion from Double to String cannot overflow.
stringVal = System.Convert.ToString(doubleVal)
outputBlock.Text &= String.Format("{0} as a String is: {1}", _
doubleVal, stringVal) & vbCrLf
Try
doubleVal = System.Convert.ToDouble(stringVal)
outputBlock.Text &= String.Format("{0} as a Double is: {1}", _
stringVal, doubleVal) & vbCrLf
Catch exception As System.OverflowException
outputBlock.Text &= String.Format( _
"Overflow in String-to-Double conversion.") & vbCrLf
Catch exception As System.FormatException
outputBlock.Text &= String.Format( _
"The string is not formatted as a Double.") & vbCrLf
Catch exception As System.ArgumentException
outputBlock.Text &= "The string is null." & vbCrLf
End Try
End Sub
public void ConvertDoubleString(double doubleVal)
{
string stringVal;
// A conversion from Double to string cannot overflow.
stringVal = System.Convert.ToString(doubleVal);
outputBlock.Text += String.Format("{0} as a string is: {1}",
doubleVal, stringVal) + "\n";
try
{
doubleVal = System.Convert.ToDouble(stringVal);
outputBlock.Text += String.Format("{0} as a double is: {1}",
stringVal, doubleVal) + "\n";
}
catch (System.OverflowException)
{
outputBlock.Text += String.Format(
"Conversion from string-to-double overflowed.") + "\n";
}
catch (System.FormatException)
{
outputBlock.Text += String.Format(
"The string was not formatted as a double.") + "\n";
}
catch (System.ArgumentException)
{
outputBlock.Text += String.Format(
"The string pointed to null.") + "\n";
}
}
