Assembly: System.Data (in System.Data.dll)
The VersionNotFoundException type exposes the following members.
| Name | Description | |
|---|---|---|
![]() ![]() | VersionNotFoundException() | Initializes a new instance of the VersionNotFoundException class. |
![]() ![]() | VersionNotFoundException(String) | Initializes a new instance of the VersionNotFoundException class with the specified string. |
![]() | VersionNotFoundException(SerializationInfo, StreamingContext) | Initializes a new instance of the VersionNotFoundException class with serialization information. |
![]() ![]() | VersionNotFoundException(String, Exception) | Initializes a new instance of the VersionNotFoundException class with a specified error message and a reference to the inner exception that is the cause of this exception. |
| Name | Description | |
|---|---|---|
![]() | Data | Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.) |
![]() | 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.) |
![]() | 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.) |
| Name | Description | |
|---|---|---|
![]() ![]() | 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 | When overridden in a derived class, sets the SerializationInfo with information about the exception. (Inherited from Exception.) |
![]() ![]() | 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 | Creates and returns a string representation of the current exception. (Inherited from Exception.) |
| Name | Description | |
|---|---|---|
![]() | SerializeObjectState | Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception.) |
The following example creates a DataTable with one DataColumn and ten DataRow objects. After deleting a DataRow, trying to return the removed row's current version causes a VersionNotFoundException exception being thrown.
private void DemonstrateVersionNotFoundException() { // Create a DataTable with one column. DataTable table = new DataTable("NewTable"); DataColumn column = new DataColumn("NewColumn"); table.Columns.Add(column); DataRow newRow; for(int i = 0;i <10;i++) { newRow = table.NewRow(); newRow["NewColumn"] = i; table.Rows.Add(newRow); } table.AcceptChanges(); try { Console.WriteLine("Trying..."); DataRow removedRow = table.Rows[9]; removedRow.Delete(); removedRow.AcceptChanges(); // Try to get the Current row version. Console.WriteLine(removedRow[0,DataRowVersion.Current]); } catch(System.Data.VersionNotFoundException) { Console.WriteLine("Current version of row not found."); } }
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
