通过SqlDataAdapter 插入DataSet中的数据到数据库

关于 通过SqlDataAdapter 插入DataSet中的数据到数据库 有两种方法：

(1)

使用SqlCommandBuilder

SqlConnection conn=new SqlConnection();
conn.ConnectionString=ConfigurationManager.ConnectionStrings["TestDBConnectionString"].ConnectionString;
conn.Open();
SqlCommand cmd=new SqlCommand();
cmd.CommandText="select * from UserInfo";
cmd.CommandType=CommandType.Text;
cmd.Connection=conn;
SqlDataAdapter adapter = new SqlDataAdapter();
SqlCommandBuilder build = new SqlCommandBuilder(adapter);
DataSet ds = new DataSet();
adapter.SelectCommand = cmd;
adapter.Fill(ds);
DataRow row = ds.Tables[0].NewRow();
row["UserName"] = "lhhhhhhhhhhhh";
row["UserSex"] = 0;
ds.Tables[0].Rows.Add(row);
adapter.Update(ds);
adapter.Dispose();
cmd.Dispose();
conn.Dispose();

(2) 使用 sqldataadapter 中的 insertcommand：

SqlConnection conn=new SqlConnection();
conn.ConnectionString=ConfigurationManager.ConnectionStrings["TestDBConnectionString"].ConnectionString;
conn.Open();
SqlCommand cmd=new SqlCommand();
cmd.CommandText="select * from UserInfo";
cmd.CommandType=CommandType.Text;
cmd.Connection=conn;
SqlDataAdapter adapter = new SqlDataAdapter();
DataSet ds = new DataSet();
adapter.SelectCommand = cmd;
adapter.Fill(ds);
DataRow row = ds.Tables[0].NewRow();
row["UserName"] = "ccccjjjjjjjjjjj";
row["UserSex"] = 0;
ds.Tables[0].Rows.Add(row);
cmd.CommandText = "insert into UserInfo values(@username,@usersex)";
adapter.InsertCommand=cmd;
cmd.Parameters.Add(new SqlParameter("@username",SqlDbType.VarChar,50));
cmd.Parameters.Add(new SqlParameter("@usersex", SqlDbType.Bit));
cmd.Parameters[0].SourceColumn = "UserName";
cmd.Parameters[0].SourceVersion = DataRowVersion.Original;
cmd.Parameters[1].SourceColumn = "UserSex";
cmd.Parameters[1].SourceVersion = DataRowVersion.Original;
adapter.Update(ds);
adapter.Dispose();
cmd.Dispose();
conn.Dispose();
