.net和訪問數據庫連接問題？

Question

使用Visual Studio 2013爲網絡創建一個使用空白表格一個網站，我剛開始和我與（我認爲）是掙扎Access數據庫的連接。我創建了可以在數據庫中提取和更新數據的表單，但是當我嘗試使用文本框的插入數據創建註冊表單時，我收到了以下錯誤消息。我知道這段代碼並不好我剛開始學習這個！請任何人都可以幫我嗎？

錯誤消息：

System.ArgumentException：關鍵字不支持： '供應商'。在 System.Data.Common.DbConnectionOptions.ParseInternal（哈希表 parsetable，字符串的connectionString，布爾buildChain，哈希表 同義詞，布爾firstKey）在 System.Data.Common.DbConnectionOptions..ctor（字符串的connectionString， Hashtable的同義詞，布爾useOdbcRules）在 System.Data.SqlClient.SqlConnectionString..ctor（字符串 的connectionString）在 System.Data.SqlClient.SqlConnectionFactory.CreateConnectionOptions（字符串 的connectionString，DbConnectionOptions以前）在 System.Data.ProviderBase.DbConnectionFactory.GetConnectionPoolGroup（ DbConnectionPoolKey 鍵，DbConnectionPoolGroupOptions poolOptions，DbConnectionOptions &個 userConnectionOptions）在 System.Data.SqlClient.SqlConnection.ConnectionString_Set（DbConnectionPoolKey 鍵）在 System.Data.SqlClient.SqlConnection.set_ConnectionString（字符串值） 在System.Data.SqlClient.SqlConnection..ctor（字符串的connectionString ， SqlCredential憑證）在 System.Data.SqlClient.SqlConnection..ctor（字符串的connectionString）在 Registration.Button1_Click（對象發件人，EventArgs e）如 C：\用戶\婁\文件\的Visual Studio 2013 \網站已\ BeautyExperts \ Registration.aspx.cs：線22

您使用SqlConnection訪問Ole因此錯誤。改變你的C＃代碼使用OleDbConnection和相關命令即OleDbCommand，並預期它應該只是工作。

using (OleDbConnection connection = new OleDbConnection("Your Connection String")) 
{ 
    //Do something here 
}
