我有同样的问题，我做的是创建一个包含数据表名称的字符串，然后将它们添加到我的命令构建器。

I had a same problem and that i did was to create a string with the names of the datatable and then adding them to my command builder.

private string GetColumnNames(DataTable dt)
        {
            string name = String.Empty;
            foreach (DataColumn dc in dt.Columns)
            {
                 name += dc.ColumnName + " NVARCHAR(50)"+", "; 
            }
            return name;

        }
        private void CreateTableFromDataTable(DataTable dt,string tablename,string columns)
        {
            string createString = "CREATE TABLE "+tablename+" ("+ columns+")"; //YOUR SQL COMMAND TO CREATE A TABLE                      
            SqlCommand create = new SqlCommand(createString, sqlconnection);
            sqlconnection.Open();            
            create.ExecuteNonQuery();
            sqlconnection.Close();

        }
