public class CqlReader : DbDataReader
The CqlReader type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Close | (Overrides DbDataReader.Close().) |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
| Dispose | Releases all resources used by the current instance of the DbDataReader class. (Inherited from DbDataReader.) |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
| GetBoolean | Gets the value of the specified column as a Boolean. (Overrides DbDataReader.GetBoolean(Int32).) |
| GetByte | Gets the value of the specified column as a byte. (Overrides DbDataReader.GetByte(Int32).) |
| GetBytes | Reads a stream of bytes from the specified column, starting at location indicated by dataOffset, into the buffer, starting at the location indicated by bufferOffset. (Overrides DbDataReader.GetBytes(Int32, Int64,Byte[], Int32, Int32).) |
| GetChar | Gets the value of the specified column as a single character. (Overrides DbDataReader.GetChar(Int32).) |
| GetChars | Reads a stream of characters from the specified column, starting at location indicated by dataOffset, into the buffer, starting at the location indicated by bufferOffset. (Overrides DbDataReader.GetChars(Int32, Int64,Char[], Int32, Int32).) |
| GetData | Returns a DbDataReader object for the requested column ordinal. (Inherited from DbDataReader.) |
| GetDataTypeName | Gets name of the data type of the specified column. (Overrides DbDataReader.GetDataTypeName(Int32).) |
| GetDateTime | Gets the value of the specified column as a DateTime object. (Overrides DbDataReader.GetDateTime(Int32).) |
| GetDecimal | Gets the value of the specified column as a Decimal object. (Overrides DbDataReader.GetDecimal(Int32).) |
| GetDouble | Gets the value of the specified column as a double-precision floating point number. (Overrides DbDataReader.GetDouble(Int32).) |
| GetEnumerator | (Overrides DbDataReader.GetEnumerator().) |
| GetFieldType | Gets the data type of the specified column. (Overrides DbDataReader.GetFieldType(Int32).) |
| GetFloat | Gets the value of the specified column as a single-precision floating point number. (Overrides DbDataReader.GetFloat(Int32).) |
| GetGuid | Gets the value of the specified column as a globally-unique identifier (GUID). (Overrides DbDataReader.GetGuid(Int32).) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetInt16 | Gets the value of the specified column as a 16-bit signed integer. (Overrides DbDataReader.GetInt16(Int32).) |
| GetInt32 | Gets the value of the specified column as a 32-bit signed integer. (Overrides DbDataReader.GetInt32(Int32).) |
| GetInt64 | Gets the value of the specified column as a 64-bit signed integer. (Overrides DbDataReader.GetInt64(Int32).) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetName | Gets the name of the column, given the zero-based column ordinal. (Overrides DbDataReader.GetName(Int32).) |
| GetOrdinal | Gets the column ordinal given the name of the column. (Overrides DbDataReader.GetOrdinal(String).) |
| GetProviderSpecificFieldType | Returns the provider-specific field type of the specified column. (Inherited from DbDataReader.) |
| GetProviderSpecificValue | Gets the value of the specified column as an instance of Object. (Inherited from DbDataReader.) |
| GetProviderSpecificValues | Gets all provider-specific attribute columns in the collection for the current row. (Inherited from DbDataReader.) |
| GetSchemaTable | (Overrides DbDataReader.GetSchemaTable().) |
| GetString | (Overrides DbDataReader.GetString(Int32).) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| GetValue | Gets the value of the specified column as an instance of Object. (Overrides DbDataReader.GetValue(Int32).) |
| GetValues | Populates an array of objects with the column values of the current row. (Overrides DbDataReader.GetValues(Object[]).) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| IsDBNull | Gets a value that indicates whether the column contains nonexistent or missing values. (Overrides DbDataReader.IsDBNull(Int32).) |
| NextResult | Advances the reader to the next result when reading the results of a batch of statements. (Overrides DbDataReader.NextResult().) |
| Read | Advances the reader to the next record in a result set. (Overrides DbDataReader.Read().) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Properties| Name | Description | |
|---|---|---|
 | Depth | (Overrides DbDataReader.Depth.) |
| FieldCount | Gets the number of columns in the current row. (Overrides DbDataReader.FieldCount.) |
| HasRows | (Overrides DbDataReader.HasRows.) |
| IsClosed | (Overrides DbDataReader.IsClosed.) |
| Item[Int32] | (Overrides DbDataReader.Item[Int32].) |
| Item[String] | (Overrides DbDataReader.Item[String].) |
| RecordsAffected | (Overrides DbDataReader.RecordsAffected.) |
| VisibleFieldCount | Gets the number of fields in the DbDataReader that are not hidden. (Inherited from DbDataReader.) |
