This issue was reported on the mailing list.
The root cause was a reentrancy issue where the _keyInfo field of the SQLiteDataReader was disposed just prior to being recreated; however, it was not subsequently set to null. Then, the GetSchemaTable method was invoked indirectly via the SQLiteKeyReader constructor, causing the code to call the AppendSchemaTable method on the disposed SQLiteKeyReader instance. mistachkin added on 2012-05-25 23:28:56 UTC: mistachkin added on 2012-05-25 23:36:18 UTC: System.NullReferenceException: Object reference not set to an instance of an object. at System.Data.SQLite.SQLiteKeyReader.AppendSchemaTable(DataTable tbl) in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLiteKeyReader.cs:line 604 at System.Data.SQLite.SQLiteDataReader.GetSchemaTable(Boolean wantUniqueInfo, Boolean wantDefaultValue) in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLiteDataReader.cs:line 1008 at System.Data.SQLite.SQLiteKeyReader..ctor(SQLiteConnection cnn, SQLiteDataReader reader, SQLiteStatement stmt) in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLiteKeyReader.cs:line 172 at System.Data.SQLite.SQLiteDataReader.LoadKeyInfo() in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLiteDataReader.cs:line 1319 at System.Data.SQLite.SQLiteDataReader.NextResult() in c:\dev\sqlite\dotnet\System.Data.SQLite\SQLiteDataReader.cs:line 1218 at System.Data.Common.DataAdapter.FillSchemaFromReader(DataSet dataset, DataTable datatable, SchemaType schemaType, String srcTable, IDataReader dataReader) at System.Data.Common.DataAdapter.FillSchema(DataSet dataSet, SchemaType schemaType, String srcTable, IDataReader dataReader) at System.Data.Common.DbDataAdapter.FillSchemaInternal(DataSet dataset, DataTable datatable, SchemaType schemaType, IDbCommand command, String srcTable, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillSchema(DataSet dataSet, SchemaType schemaType, IDbCommand command, String srcTable, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.FillSchema(DataSet dataSet, SchemaType schemaType) at _Dynamic16144.Test16144.Main() | ||||
