c# - MsAccess 数据库

Question

我试图让我connection string连接到我的 Access 数据库，但我遇到了这个问题。

当我将其写为连接字符串时：

string cs = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\prjThesis\STUD_RECORD.accdb";

反斜杠被标记为红色，并且一条错误消息指出Unrecognized escape sequence指向斜杠。

我该如何解决这个问题？

Answer 1

Use @ before the string or double slashes.

string cs = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\prjThesis\STUD_RECORD.accdb";

or

string cs = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\prjThesis\\STUD_RECORD.accdb";

Answer 2

Try with verbtaim string literals like this;

string cs = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\prjThesis\STUD_RECORD.accdb";

Or you can use double slash (\\) in your code without verbtaim literal;

string cs = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\prjThesis\\STUD_RECORD.accdb";

Answer 3

Use \\ (they mean \ in an ordinary string literal):

string cs = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\\prjThesis\\STUD_RECORD.accdb"

...or verbatim string literals:

string cs = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:\prjThesis\STUD_RECORD.accdb"
