Convert.ToString Method (SByte, IFormatProvider)
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Converts the value of the specified 8-bit signed integer to its equivalent String representation.
This API is not CLS-compliant.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
<CLSCompliantAttribute(False)> _
Public Shared Function ToString ( _
value As SByte, _
provider As IFormatProvider _
) As String
[CLSCompliantAttribute(false)]
public static string ToString(
sbyte value,
IFormatProvider provider
)
Parameters
- value
Type: System.SByte
An 8-bit signed integer.
- provider
Type: System.IFormatProvider
An IFormatProvider interface implementation that supplies culture-specific formatting information.
Return Value
Type: System.String
The String equivalent of the value of value.
Examples
The following code example converts an SByte (signed byte) value to a String with the ToString method, using an IFormatProvider object.
