本文實例講述了C#創建數據庫及導入sql腳本的方法。分享給大家供大家參考，具體如下：
C#創建數據庫：
/// <summary>/// 創建數據庫/// </summary>/// <param name="connStr">連接字符串</param>/// <param name="_strDBName">數據庫名稱</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;} C#導入sql腳本：
/// <summary>/// 導入sql腳本/// </summary>/// <param name="sqlConnString">連接數據庫字符串</param>/// <param name="varFileName">腳本路徑</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(); } }} 希望本文所述對大家C#程序設計有所幫助。
