Methods| Name | Description | |
|---|---|---|
| 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.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| ResetDbType |
Resets the DbType property to its original settings.
(Overrides DbParameterResetDbType.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Properties| Name | Description | |
|---|---|---|
 | DbType |
Gets or sets the DbType of the parameter.
(Overrides DbParameterDbType.) |
| Direction |
Gets or sets a value indicating whether the parameter is
input-only, output-only, bidirectional, or a stored procedure return value parameter.
(Overrides DbParameterDirection.) |
| IsNullable |
Gets a value indicating whether the parameter accepts null values.
(Overrides DbParameterIsNullable.) |
| ParameterName |
Gets or sets the name of the IDataParameter.
(Overrides DbParameterParameterName.) |
| Precision | [Supported in the .NET Framework 4.5.1 and later versions] Gets or sets the maximum number of digits used to represent the Value property. (Inherited from DbParameter.) |
| Scale | [Supported in the .NET Framework 4.5.1 and later versions] Gets or sets the number of decimal places to which Value is resolved. (Inherited from DbParameter.) |
| Size |
The size of the parameter.
(Overrides DbParameterSize.) |
| SourceColumn |
Gets or sets the name of the source column that is mapped
to the DataSet and used for loading or
returning the Value.
(Overrides DbParameterSourceColumn.) |
| SourceColumnNullMapping |
Sets or gets a value which indicates whether the source column is nullable.
This allows DbCommandBuilder
to correctly generate Update statements for nullable columns.
(Overrides DbParameterSourceColumnNullMapping.) |
| SourceVersion |
Gets or sets the DataRowVersion
to use when loading Value.
(Overrides DbParameterSourceVersion.) |
| Value |
