我正在使用Sync Framework 2.1。我正在实施冲突处理,但我不明白为什么它不起作用:
这是我的冲突处理代码:
public void OnErrorOccured(DbApplyChangeFailedEventArgs e)
{
if (e.Conflict.Type == DbConflictType.LocalUpdateRemoteUpdate)
{
int remoteValue = (int)e.Conflict.RemoteChange.Rows[0][e.Conflict.RemoteChange.Columns["MyValue"]];
int localValue = (int)e.Conflict.LocalChange.Rows[0][e.Conflict.LocalChange.Columns["MyValue"]];
if (remoteValue > localValue)
{
// Overwrite only MyValue column
e.Conflict.LocalChange.Rows[0][e.Conflict.LocalChange.Columns["MyValue"]] = remoteValue;
e.Action = ApplyAction.RetryApplyingRow; // Retry with new changes
// Same conflict will be raised again and again and again
}
else
{
// Overwrite entire local record
e.Action = ApplyAction.RetryWithForceWrite;
// The else is working properly
}
}
}
我还尝试使e.Conflict.RemoteChange等于e.Conflict.LocalChange,将所有值合并到两个DataTables中:
// Overwrite only MyValue column
e.Conflict.LocalChange.Rows[0][e.Conflict.LocalChange.Columns["MyValue"]] = remoteValue;
// Copy rest of all columns
e.Conflict.RemoteChange.Rows[0][1] = e.Conflict.LocalChange.Rows[0][1];
e.Conflict.RemoteChange.Rows[0][2] = e.Conflict.LocalChange.Rows[0][2];
e.Conflict.RemoteChange.Rows[0][3] = e.Conflict.LocalChange.Rows[0][3];
Bot也没有帮助。
- 我的代码出了什么问题?
- 我没有使用RetryApplyingRow找到任何好的考试。你能提供吗?
提前致谢!
