C# から SQL Server 2008 に DataTable を渡すにはどうすればよいですか?

例外:

テーブル タイプ パラメータ '@CurrentTableInitial' には、有効なタイプ名が必要です。

テーブル構造:

CREATE TABLE [dbo].[RegisterChoiceUserInitial](
    [RegisterChoiceUserInitialID] [int] IDENTITY(1,1) NOT NULL,
    [UserId] [uniqueidentifier] NOT NULL,
    [RegisterChoiceUserInitialJob] [nvarchar](50) NULL,
    [RegisterChoiceUserInitialOrganization] [nvarchar](50) NULL,
    [RegisterChoiceUserInitialUnit] [nvarchar](50) NULL,
    [RegisterChoiceUserInitialMembershipType] [nvarchar](50) NULL,
    [RegisterChoiceUserInitialStart] [nvarchar](10) NULL,
    [RegisterChoiceUserInitialEnd] [nvarchar](10) NULL,
 CONSTRAINT [PK_RegisterChoiceUserInitial] PRIMARY KEY CLUSTERED 
(
    [RegisterChoiceUserInitialID] ASC
)

ユーザー定義型:

CREATE TYPE [dbo].[TableTypeInitial] AS TABLE(
    [ID] [int] NULL,
    [InitialJob] [nvarchar](50) NULL,
    [InitialOrganization] [nvarchar](50) NULL,
    [InitialUnit] [nvarchar](50) NULL,
    [InitialMembershipType] [nvarchar](50) NULL,
    [InitialMembershipStart] [nvarchar](10) NULL,
    [InitialMembershipEnd] [nvarchar](10) NULL
)

ストアド プロシージャ:

create PROCEDURE [dbo].[FinishRegisterChoiceUserInitial]
      ( @UserId                         uniqueidentifier,
       @TableVariable TableTypeInitial READONLY)
 AS
 BEGIN

 INSERT INTO [Election].[dbo].[RegisterChoiceUserInitial]
           ([UserId]
           ,[RegisterChoiceUserInitialJob]
           ,[RegisterChoiceUserInitialOrganization]
           ,[RegisterChoiceUserInitialUnit]
           ,[RegisterChoiceUserInitialMembershipType]
           ,[RegisterChoiceUserInitialStart]
           ,[RegisterChoiceUserInitialEnd])
       SELECT
             @UserId AS UserId
             ,InitialJob
             ,InitialOrganization
             ,InitialUnit
             ,InitialMembershipType
             ,InitialMembershipStart
             ,InitialMembershipEnd
       FROM
             @TableVariable   
 END

データ表：

DataTableInitial.Columns.Add(new DataColumn("ID", typeof(int)));
DataTableInitial.Columns.Add(new DataColumn("InitialJob", typeof(String)));
DataTableInitial.Columns.Add(new DataColumn("InitialOrganization", typeof(String)));
DataTableInitial.Columns.Add(new DataColumn("InitialUnit", typeof(String)));
DataTableInitial.Columns.Add(new DataColumn("InitialMembershipType", typeof(String)));
DataTableInitial.Columns.Add(new DataColumn("InitialMembershipStart", typeof(String)));
DataTableInitial.Columns.Add(new DataColumn("InitialMembershipEnd", typeof(String)));

cmd.CommandText = "EXEC FinishRegisterChoiceUserInitial @UserId, @CurrentTableInitial ";
cmd.Parameters.AddWithValue("@UserId",user.ProviderUserKey);

DataTable TableInitial=(DataTable)ViewState["CurrentTableInitial"];
SqlParameter a = cmd.Parameters.AddWithValue("@CurrentTableInitial", TableInitial);
a.SqlDbType = SqlDbType.Structured;

cmd.ExecuteNonQuery();
