Метод	Описание
Clone ( ) : Npgsql.NpgsqlParameter	Creates a new NpgsqlParameter that is a copy of the current instance.
NpgsqlParameter ( ) : System	Initializes a new instance of the NpgsqlParameter class.
NpgsqlParameter ( String parameterName, object value ) : System	Initializes a new instance of the NpgsqlParameter class with the parameter name and a value of the new NpgsqlParameter. When you specify an Object in the value parameter, the DbType is inferred from the .NET Framework type of the Object. When using this constructor, you must be aware of a possible misuse of the constructor which takes a DbType parameter. This happens when calling this constructor passing an int 0 and the compiler thinks you are passing a value of DbType. Use `Convert.ToInt32(value)` for example to have compiler calling the correct constructor.
NpgsqlParameter ( string parameterName, DbType parameterType ) : System	Initializes a new instance of the NpgsqlParameter.
NpgsqlParameter ( string parameterName, DbType parameterType, int size ) : System	Initializes a new instance of the NpgsqlParameter.
NpgsqlParameter ( string parameterName, DbType parameterType, int size, string sourceColumn ) : System	Initializes a new instance of the NpgsqlParameter.
NpgsqlParameter ( string parameterName, DbType parameterType, int size, string sourceColumn, ParameterDirection direction, bool isNullable, byte precision, byte scale, DataRowVersion sourceVersion, object value ) : System	Initializes a new instance of the NpgsqlParameter.
NpgsqlParameter ( string parameterName, NpgsqlDbType parameterType ) : System	Initializes a new instance of the NpgsqlParameter class with the parameter name and the data type.
NpgsqlParameter ( string parameterName, NpgsqlDbType parameterType, int size ) : System	Initializes a new instance of the NpgsqlParameter.
NpgsqlParameter ( string parameterName, NpgsqlDbType parameterType, int size, string sourceColumn ) : System	Initializes a new instance of the NpgsqlParameter
NpgsqlParameter ( string parameterName, NpgsqlDbType parameterType, int size, string sourceColumn, ParameterDirection direction, bool isNullable, byte precision, byte scale, DataRowVersion sourceVersion, object value ) : System	Initializes a new instance of the NpgsqlParameter.
ResetDbType ( ) : void	Reset DBType.

Описание методов

Clone() публичный Метод

Creates a new NpgsqlParameter that is a copy of the current instance.

public Clone ( ) : Npgsql.NpgsqlParameter
Результат	Npgsql.NpgsqlParameter

NpgsqlParameter() публичный Метод

Initializes a new instance of the NpgsqlParameter class.

public NpgsqlParameter ( ) : System
Результат	System

NpgsqlParameter() публичный Метод

Initializes a new instance of the NpgsqlParameter class with the parameter name and a value of the new NpgsqlParameter.

When you specify an Object in the value parameter, the DbType is inferred from the .NET Framework type of the Object.

When using this constructor, you must be aware of a possible misuse of the constructor which takes a DbType parameter. This happens when calling this constructor passing an int 0 and the compiler thinks you are passing a value of DbType. Use Convert.ToInt32(value) for example to have compiler calling the correct constructor.

public NpgsqlParameter ( String parameterName, object value ) : System
parameterName	String	The name of the parameter to map.
value	object	An Object that is the value of the NpgsqlParameter.
Результат	System
