【问题描述】：

我正在使用 EF Core 进行 sql 查询，但我的编码返回错误，

数据库设置：

字符集：latin1
排序规则：latin1_general_ci

数据库 - 引擎 InnoDb - 字符集：latin1 - 排序规则：latin1_general_ci

这是一个 MySql 数据库

存储库

    public Repository(CrmGatewayCarteirasContext context)
    {
        Context = context;
        DbSet = context.Set<TEntity>();
    }

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    public IEnumerable<TEntity> GetAll()
    {
        return DbSet.ToList();
    }

    protected virtual void Dispose(bool disposing)
    {
        if (_disposed) return;
        _disposed = true;
    }
