Represents a situation in which an attempted update fails because member values have been updated since the client last read them.
Assembly: System.Data.Linq (in System.Data.Linq.dll)
Thetype exposes the following members.
|CurrentValue||Gets the current value of the member in conflict.|
|DatabaseValue||Gets the database value of the member in conflict.|
|IsModified||Gets a value that indicates whether the member data has been changed since the last database read or refresh.|
|IsResolved||Gets a value that indicates whether the conflict has been resolved.|
|Member||Gets metadata information about the member in conflict.|
|OriginalValue||Gets the original value of the member in conflict.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|Resolve(Object)||Specifies the value to set as the current value for the member in conflict.|
|Resolve(RefreshMode)||Uses a RefreshMode parameter to automatically specify the value to set as the current value for the member in conflict.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The following example shows how to retrieve information about members in conflict.
