命名SQL序列的连接字符串中无法识别的转义序列错误

Question

使用Visual Studio 2015和SQL Server 2014。

我尝试过使用＆＃39; []＆＃39;，使用双反斜杠和＆＃39; @＆＃39;仍然会给出无法识别的转义序列错误。还有其他解决办法吗？

SqlCommand cmd = new SqlCommand("Insert into Products(Id,Name,[Description],Price,IsAvailable) Values(@Id, @Name, @Description, @Price, @IsAvailable)", "Data Source=.\MSSQLSERVER1;Initial Catalog=ProductDB;Integrated Security=True");

Answer 1

一旦你弄清楚如何正确地转义它（使用@或\），没有SqlCommand的构造函数接受一个连接字符串：

var conn=new SqlConnection(@"Data Source=.\MSSQLSERVER1;Initial Catalog=ProductDB;Integrated Security=True");
SqlCommand cmd = new SqlCommand("Insert into Products(Id,Name,[Description],Price,IsAvailable) Values(@Id, @Name, @Description, @Price, @IsAvailable)", conn);

或

var conn=new SqlConnection("Data Source=.\\MSSQLSERVER1;Initial Catalog=ProductDB;Integrated Security=True");
SqlCommand cmd = new SqlCommand("Insert into Products(Id,Name,[Description],Price,IsAvailable) Values(@Id, @Name, @Description, @Price, @IsAvailable)", conn);

Answer 2

使用字符串上的前导@转义@字符。

SqlCommand cmd = new SqlCommand(@"Insert into Products(Id,Name,[Description],Price,IsAvailable) Values(@Id, @Name, @Description, @Price)", yourConnection);
