C# OleDb判断ACCESS中是否存在表,不存在则新建

private static OleDbConnection connection;

判断HeatDataSheet表是否存在

        public static bool IsExitsTables(OleDbConnection conn)
        {
    
    

            DataTable schemaTable = conn.GetOleDbSchemaTable(OleDbSchemaGuid.Tables,
                                                             new object[] {
    
     null, null, null, "HeatDataSheet" });
            return schemaTable != null;
            
        }

OleDbConnection

public static void CreateTable()
        {
    
    
            string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data source =" + FileName;   //accdb 数据库
            connection = new OleDbConnection(connectionString);
            connection.Open();
