本文实例讲述了C#创建数据库及导入sql脚本的方法。分享给大家供大家参考，具体如下：
C#创建数据库：
/// <summary>
/// 创建数据库
/// </summary>
/// <param name="connStr">连接字符串</param>
/// <param name="_strDBName">数据库名称</param>
/// <returns></returns>
private static bool CreateDatabase(string connStr, string _strDBName)
{
bool bSuccess = false;
try
{
using (SqlConnection conMaster = new SqlConnection(connStr))
{
conMaster.Open();
// Check if the Database has existed first
string strExist = @"select * from dbo.sysdatabases where name='" + _strDBName + @"'";
SqlCommand cmdExist = new SqlCommand(strExist, conMaster);
SqlDataReader readerExist = cmdExist.ExecuteReader();
bool bExist = readerExist.HasRows;
readerExist.Close();
if (bExist)
{
string strDel = @"drop database " + _strDBName;
SqlCommand cmdDel = new SqlCommand(strDel, conMaster);
cmdDel.ExecuteNonQuery();
}
// Create the database now;
string strDatabase = "Create Database [" + _strDBName + "]";
SqlCommand cmdCreate = new SqlCommand(strDatabase, conMaster);
cmdCreate.ExecuteNonQuery();
conMaster.Close();
}
bSuccess = true;
}
catch (Exception e)
{
throw e;
}
return bSuccess;
}
</div>
C#导入sql脚本：
/// <summary>
/// 导入sql脚本
/// </summary>
/// <param name="sqlConnString">连接数据库字符串</param>
/// <param name="varFileName">脚本路径</param>
/// <returns></returns>
private static bool ExecuteSqlFile(string sqlConnString, string varFileName)
{
if (!File.Exists(varFileName))
{
return false;
}
StreamReader rs = new StreamReader(varFileName, System.Text.Encoding.Default);
ArrayList alSql = new ArrayList();
string commandText = "";
string varLine = "";
while (rs.Peek() > -1)
{
varLine = rs.ReadLine();
if (varLine == "")
{
continue;
}
if (varLine != "GO")
{
commandText += varLine;
commandText += "\r\n";
}
else
{
commandText += "";
}
}
alSql.Add(commandText);
rs.Close();
try
{
ExecuteCommand(sqlConnString, alSql);
return true;
}
catch (Exception ex)
{
throw ex;
}
}
private static void ExecuteCommand(string sqlConnString, ArrayList varSqlList)
{
using (SqlConnection conn = new SqlConnection(sqlConnString))
{
conn.Open();
//Don't use Transaction, because some commands cannot execute in one Transaction.
//SqlTransaction varTrans = conn.BeginTransaction();
SqlCommand command = new SqlCommand();
command.Connection = conn;
//command.Transaction = varTrans;
try
{
foreach (string varcommandText in varSqlList)
{
command.CommandText = varcommandText;
command.ExecuteNonQuery();
}
//varTrans.Commit();
}
catch (Exception ex)
{
//varTrans.Rollback();
throw ex;
}
finally
{
conn.Close();
}
}
}
</div>
希望本文所述对大家C#程序设计有所帮助。
