Syntax

'Declaration
Public Overrides Property Value As Object

public override Object Value { get; set; }

public:
virtual property Object^ Value {
    Object^ get () override;
    void set (Object^ value) override;
}

/** @property */

/** @property */
public void set_Value (Object value)

public override function get Value () : Object

public override function set Value (value : Object)

Property Value

An Object that is the value of the parameter. The default value is null.

Remarks

The value is bound to the SqlCeCommand that is sent to the server.

When sending a null parameter value to the server, the user must specify DBNull, not null,which is an empty object that has no value. DBNull is used to represent null values.

If the application specifies the database type, the bound value is converted to that type when the provider sends the data to the server. The provider attempts to convert any type of value if it supports the IConvertible interface. Conversion errors may result if the specified type is not compatible with the value.

Both the DbType and SqlDbType properties can be inferred by setting the Value.

The Value property is overwritten by Update.

Example

The following example creates a SqlCeParameter and sets the Value property.

Dim param As New SqlCeParameter("@Description", SqlDbType.NVarChar)
param.Value = "garden hose"

SqlCeParameter param = new SqlCeParameter("@Description", SqlDbType.NVarChar);
param.Value = "garden hose";
