C#web项目是如何连接数据库做判断的

自己程序中定义了一个数据库 *** 作的类,用的是Server2000的数据库,仅供参考:

namespace

ComtactManager

{

class

DataBase:IDisposable

{

private

SqlConnection

Sqlconn;

public

static

string

sConn

=

"server=localhost;database=HqCompact;uid=sa;pwd=";

public

void

Dispose()

{

Dispose(true);

GCSuppressFinalize(true);

}

protected

void

Dispose(bool

disposing)

{

if

(disposing)

return;

if

(Sqlconn

!=

null)

{

SqlconnDispose();

Sqlconn

=

null;

}

}

public

void

Open()

{

if

(Sqlconn

==

null)

{

Sqlconn

=

new

SqlConnection(sConn);

SqlconnOpen();

}

}

public

void

Close()

{

if

(Sqlconn

!=

null)

SqlconnClose();

}

public

DataSet

RunSelectSQL(string

sSQLString)

{

thisOpen();

DataSet

SqlDS

=

new

DataSet();

SqlDataAdapter

SqlDA

=

new

SqlDataAdapter(sSQLString,thisSqlconn);

SqlDAFill(SqlDS);

return

SqlDS;

}

public

bool

RunReaderSQL(string

sSQLString)

{

thisOpen();

SqlCommand

cmd

=

new

SqlCommand(sSQLString,

thisSqlconn);

SqlDataReader

reader

=

cmdExecuteReader();

if

(readerRead())

{

readerClose();

return

true;

}

else

{

readerClose();

return

false;

}

}

public

SqlDataReader

getReader(string

strSelect)

{

SqlCommand

cmd

=

new

SqlCommand(strSelect,Sqlconn);

SqlDataReader

reader

=

cmdExecuteReader();

return

reader;

}

public

void

RunDelOrInsSQL(string

sSQLString)

{

thisOpen();

SqlCommand

Sqlcomm

=

new

SqlCommand(sSQLString,

thisSqlconn);

SqlcommExecuteNonQuery();

}

public

void

RunProcedure(SqlCommand

cmd)

{

cmdExecuteNonQuery();

}

}

}

数据库有数据库的语言，不同的编程语言有自己不同的风格

数据库和编程语言有关联，也可以没有关联

如果你是做一个很初级的程序，或是一个根本不用数据库的程序，那你只学编程语言就行了，因为它里面不会涉及到数据库的东西；如果你的爱好是数据库方面，那你也可以只专注数据库，编程语言就不重要了，好像数据库中ORACEL是很强大的，我们班上一个男生，编程比较差，但是他ORACEL相当出色，现在他就在ORECAL公司，还挺不错的呢

当然，如果你是偏向编程这一边，但是你的程序中又会去访问数据库，那你就两者都要会了，不过这种情况的对数据库的要求也不是太高，很容易就会的，但是你是很喜欢数据库那种，要深入研究的话，那个还是很有意思，也比较有难度的，就看你是怎么对待了

所以，具体要先学哪个呢，就要看你更喜欢哪方面些了，我觉得应该不是很重要的吧。不过，学校里面倒是一般都是先学基础的编程语言的
