使用 .net 内核将数据插入访问数据库

Question

I am trying to insert data to Access 365 in .net core API. Below is what I did to insert the data, but I am getting an error saying that:

The type or namespace name 'OleDbConnection' does not exist in the namespace 'System.Data.OleDb' (are you missing an assembly reference?)

I added the assembly reference to:

    using System.Data;
    using System.Data.Odbc;
    using System.Data.OleDb

Below is my partial C# code:

  public void PrimeAccessRules()
        {
            List<RecLoad> recList = new List<RecLoad>();
            recList = getPrimeData();
            System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
            conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;" +
        @"Data source= C:\Users\test\recload.accdb";

            try
            {
                conn.Open();
            }
        }

The error is coming right on this line:

System.Data.OleDb.**OleDbConnection**

saying that OleDbConnection does not exists

Any help will be highly apprecaited.

Answer 1

The types in the System.Data.OleDb namespace are part of the System.Data assembly in .NET Framework, but they're not included in .NET Core or .NET Standard. Since you're targetting one of the latter two (.NET Core), you'll need to add the System.Data.OleDb package to your project.
