.NET SQL CE核心 - 没有足够的存储空间来完成此操作

Question

我正在使用SQL CE将数据存储在我的应用程序中。我得到了与下面的代码错误执行它周边的3000次后：

“没有足够的存储是可用于完成此操作”

的错误是发生在一个LIVE应用。

SqlCeConnection connection; 
SqlCeTransaction transaction; 

try 
{ 
    connection = new SqlCeConnection(connectionString); 
    connection.Open(); 
    transaction = connection.BeginTransaction(); 
    SqlCeCommand deleteCmd = connection.CreateCommand(); 
    deleteCmd.CommandText ="Delete from EJData where ID=@id"; 
    deleteCmd.Parameters.Add("@id", SqlDbType.Int, Int32.MaxValue.ToString().Length, "ID"); 
    adapter.DeleteCommand = deleteCmd; 
    adapter.DeleteCommand.Transaction = transaction; 
    DataRow[] r = dataSet.Tables[0].Select("ID >=" + firstRecordID + " and ID<=" + lastRecordID); 
    foreach (DataRow row in r) 
    { 
     row.Delete(); 
    } 

    adapter.Update(dataSet,"EJData"); 
    transaction.Commit(CommitMode.Immediate); 
    transaction.Dispose(); 
    transaction = null; 
} 

catch (...) 

{ 
    ... 
} 

finally 

{ 
    if (adapter.DeleteCommand != null) 
    { 
     adapter.DeleteCommand.Dispose(); 
    } 

    connection.Close(); 
}

声明参数使用时： deleteCmd.Parameters.Add（ “@ ID”，SqlDbType.Int， “ID”）;
