ScriptDom

最简单（也是最可靠）的解决方案是使用T-SQL解析器。好消息是您不必编写它，只需添加对以下内容的引用：

• Microsoft.Data.Schema.ScriptDom
• Microsoft.Data.Schema.ScriptDom.Sql

然后使用代码：

static void Main(string[] args)
{
    string sql = @"
/* 
GO
*/ 
SELECT * FROM [table]

GO

SELECT * FROM [table]
SELECT * FROM [table]

GO

SELECT * FROM [table]";

    string[] errors;
    var scriptFragment = Parse(sql, SqlVersion.Sql100, true, out errors);
    if (errors != null)
    {
        foreach (string error in errors)
        {
            Console.WriteLine(error);
            return;
        }
    }

    TSqlScript tsqlScriptFragment = scriptFragment as TSqlScript;
    if (tsqlScriptFragment == null)
        return;

    var options = new SqlScriptGeneratorOptions { SqlVersion = SqlVersion.Sql100, KeywordCasing = KeywordCasing.PascalCase };

    foreach (TSqlBatch batch in tsqlScriptFragment.Batches)
    {
        Console.WriteLine("--");
        string batchText = ToScript(batch, options);
        Console.WriteLine(batchText);                
    }
}

public static TSqlParser GetParser(SqlVersion level, bool quotedIdentifiers)
{
    switch (level)
    {
        case SqlVersion.Sql80:
            return new TSql80Parser(quotedIdentifiers);
        case SqlVersion.Sql90:
            return new TSql90Parser(quotedIdentifiers);
        case SqlVersion.Sql100:
            return new TSql100Parser(quotedIdentifiers);
        case SqlVersion.SqlAzure:
            return new TSqlAzureParser(quotedIdentifiers);
        default:
            throw new ArgumentOutOfRangeException("level");
    }
}

public static IScriptFragment Parse(string sql, SqlVersion level, bool quotedIndentifiers, out string[] errors)
{
    errors = null;
    if (string.IsNullOrWhiteSpace(sql)) return null;
    sql = sql.Trim();
    IScriptFragment scriptFragment;
    IList<ParseError> errorlist;
    using (var sr = new StringReader(sql))
    {
        scriptFragment = GetParser(level, quotedIndentifiers).Parse(sr, out errorlist);
    }
    if (errorlist != null && errorlist.Count > 0)
    {
        errors = errorlist.Select(e => string.Format("Column {0}, Identifier {1}, Line {2}, Offset {3}",
                                                        e.Column, e.Identifier, e.Line, e.Offset) +
                                            Environment.NewLine + e.Message).ToArray();
        return null;
    }
    return scriptFragment;
}

public static SqlScriptGenerator GetScripter(SqlScriptGeneratorOptions options)
{
    if (options == null) return null;
    SqlScriptGenerator generator;
    switch (options.SqlVersion)
    {
        case SqlVersion.Sql80:
            generator = new Sql80ScriptGenerator(options);
            break;
        case SqlVersion.Sql90:
            generator = new Sql90ScriptGenerator(options);
            break;
        case SqlVersion.Sql100:
            generator = new Sql100ScriptGenerator(options);
            break;
        case SqlVersion.SqlAzure:
            generator = new SqlAzureScriptGenerator(options);
            break;
        default:
            throw new ArgumentOutOfRangeException();
    }
    return generator;
}

public static string ToScript(IScriptFragment scriptFragment, SqlScriptGeneratorOptions options)
{
    var scripter = GetScripter(options);
    if (scripter == null) return string.Empty;
    string script;
    scripter.GenerateScript(scriptFragment, out script);
    return script;
}

SQL Server管理对象

添加对以下内容的引用：

• Microsoft.SqlServer.Smo
• Microsoft.SqlServer.ConnectionInfo
• Microsoft.SqlServer.Management.Sdk.Sfc

然后，您可以使用以下代码：

using (SqlConnection connection = new SqlConnection("Server=(local);Database=Sample;Trusted_Connection=True;"))
{
    ServerConnection svrConnection = new ServerConnection(connection);
    Server server = new Server(svrConnection);
    server.ConnectionContext.ExecuteNonQuery(script);
}

CodeFluent运行时

CodeFluent运行时数据库有一个小的sql文件解析器。它不处理复杂的情况，但是例如支持注释。

using (StatementReader statementReader = new CodeFluent.Runtime.Database.Management.StatementReader("GO", Environment.NewLine, inputStream))
{
    Statement statement;
    while ((statement = statementReader.Read(StatementReaderOptions.Default)) != null)
    {
        Console.WriteLine("-- ");
        Console.WriteLine(statement.Command);
    }
}

或更简单

new CodeFluent.Runtime.Database.Management.SqlServer.Database("connection string")
      .RunScript("path", StatementReaderOptions.Default);
