未找到 Clickhouse 数据源名称且没有默认驱动程序

Question

我正在尝试通过 odbc (clikhouse-odbc) 从 c#+.Net 进行连接。

下面是我的代码

var builder = new OdbcConnectionStringBuilder();
builder.Driver =
"E:\...\clickhouse-odbc-master\vs\x64\clickhouseodbc.dll";
builder.Add("SERVER", "....");
builder.Add("DATABASE", "default");
builder.Add("PORT", 8123);
builder.Add("FRAMED", 0);
var connection = new OdbcConnection("Driver = Click House ANSI; Host = ***; Port =***");
//Also tried below
//var connection = new OdbcConnection(builder.ConnectionString);
connection.Open();
return connection;

当我运行时，我有异常：

System.Data.Odbc.OdbcException: '错误 [IM002] [Microsoft][ODBC 驱动程序 Manager] 未找到数据源名称且未指定默认驱动程序。

我也安装了驱动并配置如下图

我必须添加 builder.Driver 如下：

      var builder = new OdbcConnectionStringBuilder();
        builder.Driver =
            "E:\<path>\clickhouseodbc.dll";
        builder.Add("SERVER", "...");
        builder.Add("DATABASE", "default");
        builder.Add("PORT", 8123);
        builder.Add("FRAMED", 0);
        builder.Driver = "ClickHouse ANSI";
        var connection = new OdbcConnection(builder.ConnectionString);
        connection.Open();
