OdbcParameter コンストラクター

public:
 OdbcParameter();

public OdbcParameter ();

Public Sub New ()

例

次の例では、を作成 OdbcParameter し、そのプロパティの一部を設定します。The following example creates an OdbcParameter and sets some of its properties.

public void CreateOdbcParameter()
{
   OdbcParameter parameter = new OdbcParameter();
   parameter.ParameterName = "Description";
   parameter.OdbcType = OdbcType.VarChar;
   parameter.Direction = ParameterDirection.Output;
   parameter.Size = 88;
}

Public Sub CreateOdbcParameter()
    Dim parameter As New OdbcParameter()
    parameter.ParameterName = "Description"
    parameter.OdbcType = OdbcType.VarChar
    parameter.Direction = ParameterDirection.Output
    parameter.Size = 88
End Sub 

注釈

基本コンストラクターは、すべてのフィールドを既定値に初期化します。The base constructor initializes all fields to their default values.

注釈

コンストラクターのこのオーバーロードを使用して整数のパラメーター値を指定する場合は、注意が必要 OdbcParameter です。Use caution when you are using this overload of the OdbcParameter constructor to specify integer parameter values. このオーバーロードは Object 型の value を受け取るため、次の C# の例のように、値が 0 の場合に整数値を Object 型に変換する必要があります。Because this overload takes a value of type Object, you must convert the integral value to an Object type when the value is zero, as the following C# example demonstrates.

Parameter = new OdbcParameter("@pname", Convert.ToInt32(0));  

この変換を実行しない場合、コンパイラは、コンストラクターのオーバーロードを呼び出そうとしていることを前提としてい OdbcParameter.OdbcParameter ます。If you do not perform this conversion, the compiler assumes that you are trying to call the OdbcParameter.OdbcParameter constructor overload.
