[求助]从索引 0 处开始，初始化字符串的格式不符合规范

[lbergstrom]

我用编程的方式创建一个SqlDataSource,为什么DataBind时就:从索引 0 处开始，初始化字符串的格式不符合规范 了呢?

代码如下:

if (!IsPostBack)
{
SqlDataSource sds = new SqlDataSource();
sds.ConnectionString = "Rocket";
sds.DataSourceMode = SqlDataSourceMode.DataReader;
sds.SelectCommandType = SqlDataSourceCommandType.Text;
sds.SelectCommand = "SELECT [CommentId], [Text], [Time], [UserId] FROM [TopicComments]";

Repeater1.DataSource = sds;
Repeater1.DataBind(); // 运行到这句就会异常了
}

请大哥们帮帮忙啊,谢谢了!!

Rocket是什么？

[lbergstrom]

晕,应该是 ConfigurationManager.ConnectionStrings["Rocket"]
我居然直接写成了sds.ConnectionString = "Rocket";

这种小问题搞了半天没看出来.
还是旁观者清啊,早知道早点发CSDN上来,呵呵

我的代码是这样写的:


public conn()
{


//获取Web.Config数据库连接字符串
SqlConnection SqlConn = new SqlConnection(ConfigurationManager.ConnectionStrings["connroom"].ConnectionString.ToString ());
//构造函数创建连接，并打开连接
con = new SqlConnection(SqlConn.ToString ());
con.Open(); //打开链接
}
//执行SQL语句:插入、修改
