一些DotNet的小知识点记录
在DataTable表中添加列：
DataTable workTable = new DataTable("Customers");
DataColumn workCol = workTable.Columns.Add("CustID", typeof(Int32));
workCol.AllowDBNull = false;
workCol.Unique = true;
workTable.Columns.Add("CustLName", typeof(String));
workTable.Columns.Add("CustFName", typeof(String));
workTable.Columns.Add("Purchases", typeof(Double));
查类库的小工具：在.net命令提示符下有个命令Wincv，是查.net类库的小工具。
DataTable workTable = new DataTable("Customers");DataColumn workCol = workTable.Columns.Add("CustID", typeof(Int32));workCol.AllowDBNull = false;workCol.Unique = true;workTable.Columns.Add("CustLName", typeof(String));workTable.Columns.Add("CustFName", typeof(String));workTable.Columns.Add("Purchases", typeof(Double));查类库的小工具：在.net命令提示符下有个命令Wincv，是查.net类库的小工具。
