Throws an exception for a Win32 error code.
Assembly: System (in System.dll)
Thetype exposes the following members.
|Win32Exception||Initializes a new instance of the class with the last Win32 error that occurred.|
|Win32Exception(Int32)||Initializes a new instance of the class with the specified error.|
|Win32Exception(String)||Initializes a new instance of the class with the specified detailed description.|
|Win32Exception(Int32, String)||Initializes a new instance of the class with the specified error and the specified detailed description.|
|Win32Exception(SerializationInfo, StreamingContext)||Initializes a new instance of the class with the specified context and the serialization information.|
|Win32Exception(String, Exception)||Initializes a new instance of the class with the specified detailed description and the specified exception.|
|Data||Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)|
|ErrorCode||Gets the HRESULT of the error. (Inherited from ExternalException.)|
|HelpLink||Gets or sets a link to the help file associated with this exception. (Inherited from Exception.)|
|HResult||Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)|
|InnerException||Gets the Exception instance that caused the current exception. (Inherited from Exception.)|
|Message||Gets a message that describes the current exception. (Inherited from Exception.)|
|NativeErrorCode||Gets the Win32 error code associated with this exception.|
|Source||Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.)|
|StackTrace||Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.)|
|TargetSite||Gets the method that throws the current exception. (Inherited from Exception.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetBaseException||When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetObjectData||Sets the SerializationInfo object with the file name and line number at which this occurred. (Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).)|
|GetType||Gets the runtime type of the current instance. (Inherited from Exception.)|
In XNA Framework 3.0, this member is inherited from Object.GetType.
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that contains the HRESULT of the error. (Inherited from ExternalException.)|
In XNA Framework, this member is overridden by ToString.
Win32 error codes are translated from their numeric representations into a system message when they are displayed. Use NativeErrorCode to access the numeric representation of the error code associated with this exception. For more information about the error codes, see "Win32 Error Codes" in the Platform SDK documentation at http://msdn.microsoft.com.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
The following code example shows how to catch a Win32 exception and interpret its content. The example attempts to start a nonexistent executable, which results in a Win32 exception. Upon catching the exception, the example fetches the respective error message, code, and origin of the exception.
Try Dim myProc As New System.Diagnostics.Process() myProc.StartInfo.FileName = "c:\nonexist.exe" 'Attempting to start a non-existing executable myProc.Start() 'Start the application and assign it to the process component. Catch w As System.ComponentModel.Win32Exception Console.WriteLine(w.Message) Console.WriteLine(w.ErrorCode.ToString()) Console.WriteLine(w.NativeErrorCode.ToString()) Console.WriteLine(w.StackTrace) Console.WriteLine(w.Source) Dim e As New Exception() e = w.GetBaseException() Console.WriteLine(e.Message) End Try
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
