我可以将这三个相似的函数组合成一个函数吗？

Question

我可以将下面三个非常相似的函数组合成一个函数吗？

这三个函数都更新数据库中的特定列。update语句中的匿名对象用于更新相应的列。匿名对象中的成员名称不应更改，因为它是数据库中列的名称。

我使用ormlite-servicestack进行数据库连接。数据库I使用微软SQLServer 2012。

功能1：

//Updating the call status.
private void UpdateCallStatus(string claimId, bool isDisconnected)
{
    _LogFactory.LogInfo(this.GetType(), "Updating call status....\n");

    IDbConnectionFactory maConnectionFactory = new DatabaseConnection().getConnection();
    using (var db = maConnectionFactory.Open())
    {
        db.Update<IVRSCallDetails>(new { IsDisconnected = isDisconnected }, where: callDetail => callDetail.ClaimId == claimId);
    }
}

功能2：

//Updating the selected dtmf by the client using the claimid.
private void UpdateDtmf(string claimId, string selectedDtmf)
{
    _LogFactory.LogInfo(this.GetType(), "Updating Selected DTMF:" + selectedDtmf + "\n");

    IDbConnectionFactory maConnectionFactory = new DatabaseConnection().getConnection();
    using (var db = maConnectionFactory.Open())
    {
        db.Update<IVRSCallDetails>(new { SelectedDTMF = selectedDtmf }, where: callDetail => callDetail.ClaimId == claimId);
    }
}

功能3：

//Updating the isCallMade value..
private void updateIsCallMade(string claimId, bool isCallMade)
{
    _LogFactory.LogInfo(this.GetType(), "Call has been made to the client with claim id: " + claimId + "\n");

    IDbConnectionFactory maConnectionFactoruy = new DatabaseConnection().getConnection();
    using (var db = maConnectionFactoruy.Open())
    {
        db.Update<IVRSCallDetails>(new { IsCallMade = isCallMade }, where: callDetail => callDetail.ClaimId == claimId);
    }
}

Answer 1

您可以将其更改为泛型方法(以便能够传递类型)，还可以将第二个参数更改为Func<object>以生成匿名对象。

private void updateData<T>(string claimId, Func<object> data)
{
    _LogFactory.LogInfo(this.GetType(), "Call has been made to the client with claim id: " + claimId + "\n");

    IDbConnectionFactory maConnectionFactoruy = new DatabaseConnection().getConnection();
    using (var db = maConnectionFactoruy.Open())
    {
        db.Update<T>(data(), where: callDetail => callDetail.ClaimId == claimId);
    }
}

用法

updateData<IVRSCallDetails>("123", () => new { IsCallMade = true});
updateData<IVRSCallDetails>("123", () => new { SelectedDTMF = selectedDtmf});
