我收到了错误

＆＃39;附近的语法不正确。＆＃39;。关键字＆＃39;与＆＃39;附近的语法不正确。如果此语句是公用表表达式，xmlnamespaces子句或更改跟踪上下文子句，则必须以分号结束前一个语句。

Answer 1

您无法使用AttachDbFileName=方法，然后使用基于服务器的命令，例如backup database ....

如果要备份SQL Server数据库，则必须将其附加到服务器，并且需要连接到服务器并发出该命令：

// Connect to "master" database
string con = @"server=.\SQLEXPRESS;database=master;Integrated Security=True;";

SqlConnection connect = new SqlConnection(con);

SqlCommand ommand = new SqlCommand(@"backup database Garment to disk = N'E:\Garment.bak' with init,stats=10", connect);

connect.Open();
command.ExecuteNonQuery();
connect.Close();

Answer 2

你错过了反斜杠E：Garment.bak应该是E：\ Garment.bak

command = new SqlCommand(@"backup database Garment.mdf to disk ='E:\Garment.bak' with init,stats=10", connect);
