.NET Framework Class Library

FormatException Class

The exception that is thrown when the format of an argument does not meet the parameter specifications of the invoked method.

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

Syntax

Visual Basic (Declaration)

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Class FormatException _
    Inherits SystemException

Visual Basic (Usage)

Dim instance As FormatException

[SerializableAttribute]
[ComVisibleAttribute(true)]
public class FormatException : SystemException

Visual C++

[SerializableAttribute]
[ComVisibleAttribute(true)]
public ref class FormatException : public SystemException

JScript

public class FormatException extends SystemException

Remarks

FormatException is thrown when the format of an argument in a method invocation does not match the format of the corresponding formal parameter type. For example, if a method specifies a String parameter consisting of two digits with an embedded period, passing a corresponding string argument containing only two digits to that method would cause FormatException to be thrown.

FormatException uses the HRESULT COR_E_FORMAT, which has the value 0x80131537.

For a list of initial property values for an instance of FormatException, see the FormatException constructors.
