如何使用自定义表格名称在C＃中插入

Question

这是我尝试的部分代码

SqlConnection con = new SqlConnection(@"Data Source=ANSARI-PC\;Initial Catalog=BMS;Integrated Security=True");
    string tname = idc + "-InvoiceT";
    string sql = "select count(*) from '"+ tname + "' ";
    con.Open();
    SqlCommand sda = new SqlCommand(sql, con);
    SqlDataReader myreader;
    myreader = sda.ExecuteReader();
    int lid;  

对于上述代码，我收到此错误，表示“ 2-InvoiceT”附近的语法不正确 2-InvoiceT是数据库“ idc”中的表名，包含2作为值。

Answer 1

更改

string sql = "select count(*) from '"+ tname + "' ";

到

string sql = "select count(*) from ["+ tname + "] ";
