Question

我有一个看起来像

的Sql Server 2008 R2连接字符串

  <add name="DBConnectionString"
Data Source=XXXX;uid=rp1;pwd=XXXX;Initial Catalog=XXX;"/>

尝试使用EnterpriseLibrary.Data创建新的SQLDatabase实例时出现上述错误。

connString =ConnectionStrings.ConnectionStrings["DBConnectionString"];
Database objDB = new SqlDatabase(connString);

connString具有以下内容

Data Source=AYZ;Initial Catalog=AYZ;User ID=AYZ;Password=AYZ;

详细例外情况如下：

System.FormatException was unhandled by user code
  Message=Invalid character in a Base-64 string.
  Source=mscorlib

  InnerException:

我也试过加密连接字符串。它仍然返回相同的错误。我也试过硬编码连接字符串。
