從ASP/C＃Web表單插入數據到Access數據庫

我正在ASP/C＃中編寫一個頁面，我必須採取我創建的表單並將其插入MS Access數據庫。在MS Access數據庫是建立具有以下字段：從ASP/C＃Web表單插入數據到Access數據庫

ID, UserName, Passwrd, FirstName, LastName, Address, Address2, City, State, ZipCode, Email, Gender, Age, ShirtSize, PantSize, EmailSubscribe.

，我發現了以下錯誤：

Exception Details: System.Data.OleDb.OleDbException: No value given for one or more required parameters.

我無法弄清楚哪個參數缺少值。這裏是堆棧跟蹤：

[ OleDbException (0x80040e10): No value given for one or more required parameters.] 
    System.Data.OleDb.OleDbCommand.ExecuteCommandTextErrorHandling(OleDbHResult hr) +992156 
    System.Data.OleDb.OleDbCommand.ExecuteCommandTextForSingleResult(tagDBPARAMS dbParams, Object& executeResult) +255 
    System.Data.OleDb.OleDbCommand.ExecuteCommandText(Object& executeResult) +188 
    System.Data.OleDb.OleDbCommand.ExecuteCommand(CommandBehavior behavior, Object& executeResult) +58

    System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +36 
    System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565

這裏是代碼隱藏頁：

       { 
        if(Page.IsValid) 
        {

是'ID'確實是一個自動增量字段或您需要設置值「手動「？ – Corak 2013-05-13 13:12:11

也許一個或多個列的命名有所不同？ – Steve 2013-05-13 13:13:28

試試這個

string provider = ConfigurationManager.ConnectionStrings["databaseConnString"].ProviderName; 

     DbProviderFactory factory = DbProviderFactories.GetFactory(provider); 

     //Open Connection 
     DbConnection conn = factory.CreateConnection(); 

     //Assign Connection String 
     conn.ConnectionString = ConfigurationManager.ConnectionStrings["databaseConnString"].ConnectionString; 
     //Connection Open 
     conn.Open(); 

     //Initialize Command 
     DbCommand comm = conn.CreateCommand(); 
     //Tell command which connection it will use 
     comm.Connection = conn; 
     //Give command SQL to execute 
     comm.CommandText ="Insert into userinfo(UserName, Passwrd, FirstName, LastName, Address, Address2, City, State, ZipCode, Email, Gender, Age, ShirtSize, PantSize, EmailSubscribe) values(@UserName, @Passwrd, @FirstName, @LastName, @Address, @Address2, @City, @State, @ZipCode, @Email, @Gender, @Age, @ShirtSize, @PantSize, @EmailSubscribe)";      


     SqlParameter userName = new SqlParameter("@UserName", SqlDbType.VarChar); 
     userName .Value = userName.Text; 
     comm.Parameters.Add(userName); 

     SqlParameter password = new SqlParameter("@Passwrd", SqlDbType.VarChar); 
     password .Value = password.Text; 
     comm.Parameters.Add(password); 

     SqlParameter firstName = new SqlParameter("@FirstName", SqlDbType.VarChar); 
     firstName .Value = FirstName.Text; 
     comm.Parameters.Add(firstName); 

     SqlParameter lastName = new SqlParameter("@LastName", SqlDbType.VarChar); 
     lastName .Value = lastName.Text; 
     comm.Parameters.Add(lastName);

     address.Value = address.Text; 
     comm.Parameters.Add(address); 

     SqlParameter address2 = new SqlParameter("@Address2", SqlDbType.VarChar); 
     address2.Value = address2.Text; 
     comm.Parameters.Add(address2); 

     SqlParameter city = new SqlParameter("@City", SqlDbType.VarChar); 
     city.Value = city.Text; 
     comm.Parameters.Add(city); 

     SqlParameter state = new SqlParameter("@State", SqlDbType.VarChar); 
     state.Value = state.Text; 
     comm.Parameters.Add(state); 

     SqlParameter zipCode = new SqlParameter("@ZipCode", SqlDbType.VarChar); 
     zipCode.Value = zipCode.Text; 
     comm.Parameters.Add(zipCode); 

     SqlParameter email = new SqlParameter("@Email", SqlDbType.VarChar); 
     email.Value = email.Text; 
     comm.Parameters.Add(email); 

     SqlParameter genderRadioGroup = new SqlParameter("@GenderRadioGroup", SqlDbType.VarChar); 
     genderRadioGroup.Value = genderRadioGroup.Text; 
     comm.Parameters.Add(genderRadioGroup); 

     SqlParameter age = new SqlParameter("@Age", SqlDbType.VarChar); 
     age.Value = age.Text; 
     comm.Parameters.Add(age); 

     SqlParameter drpShirtSizeCategory = new SqlParameter("@ShirtSize", SqlDbType.VarChar); 
     drpShirtSizeCategory.Value = drpShirtSizeCategory.Text; 
     comm.Parameters.Add(drpShirtSizeCategory); 

     SqlParameter drpPantSizeCategory = new SqlParameter("@PantSize", SqlDbType.VarChar); 
     drpPantSizeCategory.Value = drpPantSizeCategory.Text; 
     comm.Parameters.Add(drpPantSizeCategory); 

     SqlParameter emailRadioGroup = new SqlParameter("@EmailSubscribe", SqlDbType.VarChar); 
     emailRadioGroup.Value = EmailRadioGroup.Text; 
     comm.Parameters.Add(emailRadioGroup); 



     //Execute command get back result via reader 
     int totalCount = comm.ExecuteNonQuery(); 

     DbCommand comm2 = conn.CreateCommand(); 
     comm2.CommandText = "Select @@Identity"; 
     comm2.Connection = conn; 

     String id = comm2.ExecuteScalar().ToString(); 
     conn.Close(); 

     lblMessage.Text = "ID of User Added = " +id;

要確保你有正確的身份，最好是調用IDENT_CURRENT（ '表名'）

DbCommand comm2 = conn.CreateCommand(); 
comm2.CommandText = "Select IDENT_CURRENT('userinfo')"; 
comm2.Connection = conn; 

String id = comm2.ExecuteScalar().ToString(); 
conn.Close();

請參閱Here一個解釋。
