推荐答案
con = new SqlConnection("user id=sa;password=arun;database=Branch Module");
永远不要使用SA帐户进行数据访问.
Never, ever use the SA account for data access.
da1 = new SqlDataAdapter("Select SNo,BranchName,BranchCode,Address1,Address2,Street,City,State,Country,ZipCode,Phone1,Phone2,Fax,EmailId,Website,Description from BranchDetails where SNo=''" + id1 + "''", con);
切勿使用字符串串联来构成查询.使用参数化查询或更好的存储过程.
并学习如何使用DataBinding
Never use string concatenation to form a query. Use parameterized queries, or better yet, stored procedures.
And learn how to use DataBinding
