使用XML的SQL連接

我想從XML文件讀取SQL信息。我得到的SQL字符串康涅狄格州這個錯誤：使用XML的SQL連接

格式的初始化字符串的不符合規範開始於索引0

XML：

<?xml version="1.0" encoding="utf-8" ?> 
<xml encoding="UTF8"> 
<configuration> 
<appsettings> 
<servername>127.0.0.1</servername> 
    <username>sa</username> 
    <password>RandomlyZE6</password> 
    <database>TelecomNames</database> 
</appsettings> 
</configuration> 
</xml>

我的代碼：

var doc = new XPathDocument(Application.StartupPath + "/DBConn.xml"); 
var navigator = doc.CreateNavigator(); 

var serverName = navigator.SelectSingleNode("//appsettings/servername"); 
// var serverIP = navigator.SelectSingleNode("//appsettings/serverport"); 
var username = navigator.SelectSingleNode("//appsettings/username"); 
var password = navigator.SelectSingleNode("//appsettings/password"); 
var database = navigator.SelectSingleNode("//appsettings/database"); 

var connection = new SqlConnection(string.Format("Data Source={0};Initial Catalog={1};User Id={2};Password={3};MultipleActiveResultSets = True;", serverName, database, username, password)); 

using (SqlConnection sqlConnection = new SqlConnection(connection.ToString())) ; 
{ 
    SqlCommand cmd = new SqlCommand("use TelecomNames SELECT xName FROM dbo.Character", connection); 
    connection.Open(); 
    cmd.ExecuteNonQuery(); 
    SqlDataReader reader = cmd.ExecuteReader(); 
    AutoCompleteStringCollection MyCollection = new AutoCompleteStringCollection(); 

    while (reader.Read()) 
    { 
    } 

    connection.Close(); 
}

錯誤在那條線上

using (SqlConnection sqlConnection = new SqlConnection(connection.ToString()))

感謝

心靈共享XML內容？ – Reniuz

完成後，我添加了它 – user3091970

您確實創建了一個'new SqlConnection'，然後使用'toString（）'創建一個新的（參見'SqlConnection sqlConnection = new SqlConnection（connection.ToString（））'） - 爲什麼？？這不能工作！ –

var doc = new XPathDocument(Application.StartupPath + "/DBConn.xml"); 

var navigator = doc.CreateNavigator(); 

var serverName = navigator.SelectSingleNode("//appsettings/servername"); 
var username = navigator.SelectSingleNode("//appsettings/username"); 
var password = navigator.SelectSingleNode("//appsettings/password"); 
var database = navigator.SelectSingleNode("//appsettings/database"); 

using (SqlConnection sqlConnection = new SqlConnection(@"Data Source=" + serverName + ";Initial Catalog=" + database + ";User Id=" + username + ";Password=" + password + ";MultipleActiveResultSets = True")) 
{ 
SqlCommand cmd = new SqlCommand("use TelecomNames SELECT xName FROM dbo.Character", connection); 
connection.Open(); 
cmd.ExecuteNonQuery(); 
SqlDataReader reader = cmd.ExecuteReader(); 
AutoCompleteStringCollection MyCollection = new AutoCompleteStringCollection(); 
while (reader.Read()) 
{ 

} 

connection.Close(); 

}
