如何备份LocalDB C# 我的数据库文件名为MyDatabase.mdf

Question

string dbpath= System.Windows.Forms.Application.StartupPath;
             string dbp = dbpath + "\\MyDatabase.Mdf";

SqlCommand cmd = new SqlCommand("backup database ['"+dbp+"'] to disk ='d:\\svBackUp1.bak' with init,stats=10",con);

cmd.ExecuteNonQuery();

Answer 1

错误是“以----开头的标识符太长。最大长度为128” 所以我用小名称“MyDb.mdf”制作“MyDatabase.mdf”。因此标识符变得小于128。

我的代码是

---

 SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["NewConnectionString"].ConnectionString);

 {
con.Open();

  string DatabaseName = Application.StartupPath + @"\MyDb.mdf";

SqlCommand cmd = new SqlCommand("BACKUP DATABASE ["+DatabaseName+"] to DISK='D:\\MyBackup.bak' ", con);


            try
            {
                cmd.ExecuteNonQuery();
                MessageBox.Show("Success");
            }
            catch (Exception Ex){
                MessageBox.Show("'"+Ex.ToString()+"'");
            }
            con.Close();

}
