The EntityParameter type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | EntityParameter() | Initializes a new instance of the EntityParameter class. |
![]() | EntityParameter(String, DbType) | Initializes a new instance of the EntityParameter class that uses the parameter name and the data type. |
![]() | EntityParameter(String, DbType, Int32) | Initializes a new instance of the EntityParameter class that uses the parameter name, the data type, and the size. |
![]() | EntityParameter(String, DbType, Int32, String) | Initializes a new instance of the EntityParameter class that uses the parameter name, the data type, the size, and the source column name. |
![]() | EntityParameter(String, DbType, Int32, ParameterDirection, Boolean, Byte, Byte, String, DataRowVersion, Object) | Initializes a new instance of the EntityParameter class that uses the parameter name, the type, the size, the direction, the precision, the scale, the source column, a DataRowVersion to use, and the value of the parameter. |
| Name | Description | |
|---|---|---|
![]() | DbType | Gets or sets the DbType of the parameter. (Overrides DbParameter::DbType.) |
![]() | Direction | Gets or sets a value that indicates whether the parameter is input-only, output-only, bidirectional, or a stored procedure return value parameter. (Overrides DbParameter::Direction.) |
![]() | IsNullable | Gets or sets a value that indicates whether the parameter accepts null values. (Overrides DbParameter::IsNullable.) |
![]() | ParameterName | Gets or sets the name of the EntityParameter. (Overrides DbParameter::ParameterName.) |
![]() | Precision | Gets or sets the maximum number of digits used to represent the Value property. |
![]() | Scale | Gets or sets the number of decimal places to which Value is resolved. |
![]() | Size | Gets or sets the maximum size, in bytes, of the data in the column. (Overrides DbParameter::Size.) |
![]() | SourceColumn | Gets or sets the name of the source column in a cached row that the EntityParameter is mapped to. (Overrides DbParameter::SourceColumn.) |
![]() | SourceColumnNullMapping | Gets or sets a value which indicates whether the source column is nullable. (Overrides DbParameter::SourceColumnNullMapping.) |
![]() | SourceVersion | Gets or sets the DataRowVersion to use when you load Value (Overrides DbParameter::SourceVersion.) |
![]() | Value | Gets or sets the value of the parameter. (Overrides DbParameter::Value.) |
| 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(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (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.) |
![]() | MemberwiseClone() | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
![]() | ResetDbType | Resets the type associated with this EntityParameter. (Overrides DbParameter::ResetDbType().) |
![]() | ToString | Gets a string that contains the ParameterName. (Overrides Object::ToString().) |
| Name | Description | |
|---|---|---|
![]() ![]() | IDbDataParameter::Precision | Indicates the precision of numeric parameters. (Inherited from DbParameter.) |
![]() ![]() | IDbDataParameter::Scale | For a description of this member, see IDbDataParameter::Scale. (Inherited from DbParameter.) |
Parameter names are not case sensitive.
