错误:无法识别的转义序列...... [英] ERROR: unrecognized escape sequence.........

问题描述

OleDbConnection conn;
OleDbCommand comm;
OleDbDataReader dr;
conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\data1\jana.mdb");
comm = new OleDbCommand("insert into mans1 values(''" + TextBox1.Text + "'',''" + TextBox2.Text + "'')", conn);
conn.Open();
dr = comm.ExecuteReader();
conn.Close();

在这里，我遇到了有关ms访问连接字符串的错误(无法识别的转义序列).........

我也尝试了{@"Data Source = C:\ data1 \ jana.mdb" AND
数据源= C:\\ data1 \\ jana.mdb"} ......

我应该怎么做……

解决方案

尝试一下:

string str="Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\\data1\\jana.mdb";

conn = new OleDbConnection(str);

希望对您有所帮助:) br/>

试试这个

conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\data1\jana.mdb");

并从此处 [ ^ ]

OleDbConnection conn;
OleDbCommand comm;
OleDbDataReader dr;
conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\data1\jana.mdb");
comm = new OleDbCommand("insert into mans1 values(''" + TextBox1.Text + "'',''" + TextBox2.Text + "'')", conn);
conn.Open();
dr = comm.ExecuteReader();
conn.Close();

Here i got a error about the ms access connection string(unrecognized escape sequence).........

Also i tried { @"Data Source=C:\data1\jana.mdb" AND
"Data Source=C:\\data1\\jana.mdb" }......

what should i do......

解决方案

try this:

string str="Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\\data1\\jana.mdb";

conn = new OleDbConnection(str);

hope this helps :)

Collect your connection string in String veriable and runtime check what you have get in string veriable, u may get like (c:data1jana.mdb)

hi,
try this

conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\data1\jana.mdb");

and also check your connection string from here[^]
