KeyNotFoundException Constructor (String, Exception)

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Initializes a new instance of the KeyNotFoundException class with the specified error message and a reference to the inner exception that is the cause of this exception.

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

Syntax

'Declaration
Public Sub New ( _
    message As String, _
    innerException As Exception _
)

public KeyNotFoundException(
    string message,
    Exception innerException
)

Parameters

message
Type: System.String
The error message that explains the reason for the exception.

innerException
Type: System.Exception
The exception that is the cause of the current exception. If the innerException parameter is not nulla null reference (Nothing in Visual Basic), the current exception is raised in a catch block that handles the inner exception.

Remarks

An exception that is thrown as a direct result of a previous exception should include a reference to the previous exception in the InnerException property. The InnerException property returns the same value that is passed into the constructor, or nulla null reference (Nothing in Visual Basic) if the InnerException property does not supply the inner exception value to the constructor.

The following table shows the initial property values for an instance of the KeyNotFoundException class.

Property	Value
InnerException	The inner exception reference.
Message	The localized error message string.
