custDA.InsertCommand.Parameters.Add("@CustomerID", OdbcType.Char, 5, "CustomerID");

Question

例如正确的调用是 custDA.InsertCommand.Parameters.Add("@CustomerID",OleDbType.char, 5, "CustomerID");而我现在的调用是:custDA.InsertCommand.Parameters.Add("@CustomerID","OleDbType.char", 5, "CustomerID");参数"OleDbType.char"(字符串)怎样转变成 OleDbType.char (类型) ?

Answer 1

OleDbType 是Enum, 不是普通的类型。
OleDbType tp=(OleDbType)Enum.Parse(typeof(OleDbType),"Char",true);
