推荐答案
试试这个.. :)
1）当前上下文中不存在clearData这个名称E：\\\ n \\\\\\\\\\\\\\\\\\\\\\\ br $>
解决方案
您可以删除clearData（）;或使函数具有名称clearData（）喜欢这个...... :)
try this.. :)
1) The name 'clearData' does not exist in the current context E:\mine\WebSite8\Gridview.aspx.cs
solution
You can removeclearData();or make function having nameclearData()like this... :)
public void clearData() {
}
2）错误7当前上下文中不存在名称Label1E：\mine\WebSite8 \ GridView.aspx.cs
您可以在设计器（aspx）页面中输出Label1，也可以从代码中删除它
3）当前上下文中名称's'不存在E：\mine\WebSite8 \\ Gridview.aspx.cs
您必须将其定义为类似的字符串
2)Error 7 The name 'Label1' does not exist in the current context E:\mine\WebSite8\Gridview.aspx.cs
either you can out Label1 in your designer(aspx) page or you can remove it from your code
3) The name 's' does not exist in the current context E:\mine\WebSite8\Gridview.aspx.cs
You have to defined it as a string like that
string s = ConfigurationManager.ConnectionStrings["ChartDatabaseConnectionString"].ConnectionString;
4）当前上下文中不存在名称WebConfigurationManagerE：\mine \\ \ nWebSite8 \ GridView.aspx.cs
试试这个而不是' WebConfigurationManager '
4)The name 'WebConfigurationManager' does not exist in the current context E:\mine\WebSite8\Gridview.aspx.cs
try this instead of 'WebConfigurationManager'
string s = ConfigurationManager.ConnectionStrings["ChartDatabaseConnectionString"].ConnectionString;
