+# C# SDK对接向量数据库
+本文介绍如何使用C#语言调用openGauss向量数据库。
+
+## 环境要求
+- 使用`donet --versin`查看是否安装.NET开发工具，若无，则需安装donet-sdk
+- 安装相关库
+   ```
+    dotnet add package Pgvector
+    dotnet add package Npgsql
+   ```
+
+## 基本操作
+### 1.连接数据库
+```C#
+public NpgsqlConnection Connect(string connStr)
+{
+    var dataSourceBuilder = new NpgsqlDataSourceBuilder(connStr);
+    dataSourceBuilder.UseVector();
+    await using var dataSource = dataSourceBuilder.Build();
+    var conn = dataSource.OpenConnection();
+    conn.ReloadTypes();
+    return conn;
+}
+```
+### 2.创建表
+```C#
+public async Task CreateTableAsync(NpgsqlConnection conn)
+{
+    const string create = "CREATE TABLE items (id serial PRIMARY KEY, embedding vector(3))";
+    await using var cmd = new NpgsqlCommand(create, conn);
+    await cmd.ExecuteNonQueryAsync();
+}
+```
+
+### 3.创建索引
+```C#
+public async Task CreateIndexAsync(NpgsqlConnection conn)
+{
+    const string createIndex = "CREATE INDEX ON items USING hnsw (embedding vector_l2_ops)";
+    await using var cmd = new NpgsqlCommand(createIndex, conn);
+    await cmd.ExecuteNonQueryAsync();
+}
+```
+
+### 4.插入/删除/更新数据
+- 批量插入
+```C#
+public async Task InsertDataAsync(NpgsqlConnection conn, Vector vector)
+{
+    const string insert = "INSERT INTO items (embedding) VALUES ($1)";
+    await using var cmd = new NpgsqlCommand(insert, conn);
+    cmd.Parameters.AddWithValue(vector);
+    await cmd.ExecuteNonQueryAsync();
+}
+```
+
+- 删除
+```C#
+public async Task DeleteDataAsync(NpgsqlConnection conn, int id)
+{
+    const string delete = "DELETE FROM items WHERE id = $1";
+    await using var cmd = new NpgsqlCommand(delete, conn);
+    cmd.Parameters.AddWithValue(id);
+    await cmd.ExecuteNonQueryAsync();
+}
+```
+
+- 更新
+```C#
+public async Task UpdateDataAsync(NpgsqlConnection conn, Vector vector, int id)
+{
+    const string update = "UPDATE items SET embedding = $1 WHERE id = $2";
+    await using var cmd = new NpgsqlCommand(update, conn);
+    cmd.Parameters.AddWithValue(vector).DataTypeName = "vector";
+    cmd.Parameters.AddWithValue(id);
+    await cmd.ExecuteNonQueryAsync();
+}
+```
+
+### 5.查询
+```C#
+public async Task<System.Collections.Generic.List<(int, Vector)>> QueryAsync(NpgsqlConnection conn, Vector vector, int limit)
+{
+    const string query = "SELECT * FROM items ORDER BY embedding <-> $1 LIMIT @limit"
+    cmd = new NpgsqlCommand(query, conn);
+    cmd.Parameters.AddWithValue(vector).DataTypeName = "vector";
+    cmd.Parameters.AddWithValue(limit);
+
+    var results = new System.Collections.Generic.List<(int, Vector)>();
+    await using var reader = await cmd.ExecuteReaderAsync();
+    while (await reader.ReadAsync())
+    {
+        var id = reader.GetInt32(0);
+        var embedding = (Vector)reader.GetValue(1);
+        results.Add((id, embedding));
+    }
+    return results;
+}
+```
+
+### 6.删除表
+
+```C#
+public async Task DropTableAsync(NpgsqlConnection conn)
+{
+    const string drop = "DROP TABLE IF EXISTS items";
+    await using var cmd = new NpgsqlCommand(drop, conn)
+    await cmd.ExecuteNonQueryAsync();
+}
+```
+
+### 7.关闭连接
+```C#
+public async Task CloseConnectionAsync(NpgsqlConnection conn)
+{
+    if(conn != null)
+    {
+        await conn.CloseAsync();
+        await conn.DisposeAsync();
+    }
+}
+```
+
+## 用例
+```C#
+using System;
+using Pgvector;
+using Npgsql;
+namespace Demo
+{
+    public class Program
+    {
+        public static async Task Main(string[] args)
+        {
+            var connstr = "Host=localhost;Database=Yourdb;Port=Yourport;Username=Yourname;Password=YourPassword";
+            var dbHandler = new Program();
+            var conn = await dbHandler.Connect(connstr);
+
+            await dbHandler.CreateTableAsync(conn);
+
+            await dbHandler.CreateIndexAsync(conn);
+
+            var vectorq = new Vector(new float[] {1, 1, 1});
+            await dbHandler.InsertDataAsync(conn, vectorq);
+
+            var results = await dbHandler.QueryAsync(conn, vectorq, 10);
+
+            await dbHandler.CloseConnectionAsync(conn);
+        }
+    }
+}
+
+```
