我有一个我序列化的DTO类

Json.Serialize(MyClass)

我怎样才能排除它的公共财产？

(它必须是公开的,因为我在其他地方的代码中使用它)

我正在使用ac#controller作为web服务.

在其中我想将用户重定向到外部URL.

我该怎么做？

尝试:

System.Web.HttpContext.Current.Response.Redirect

但它不起作用.

关于SQL Server,我理解:

• var 表示内存是惰性分配的,这意味着它完全适合数据(插入时).

• MAX 意味着没有尺寸限制\限制.

那么,使用MAX时总是优先使用varchar,因为我们无论如何都不分配整个尺寸？

只有在我们想要在此DB列上强制执行约束时,我们才应该使用常量吗？

在这两种方法的上下文中,屏幕和视图有什么区别？

我有一个按钮,我想得到它的中心的x坐标.

我想这就足够了:

public int getButtonXPosition() {
    return (button.getLeft()+button.getRight())/2;
}

但是,如果我使用它会有什么不同

getLocationOnScreen()还是getLocationInWindow()？

(当然,添加按钮宽度的一半)

第一次发生在我身上.

跑过构建并得到这个错误.

当我重建其他sln所有工作正常.

我读了一些遗留代码:

if ( 1 || !Foo() )

是否有任何理由不写:

if ( !Foo() )

我在我的应用程序中使用EF.

我尝试保存\将新记录插入映射表

并得到以下错误:

Unable to update the EntitySet 'UsersLimitationToCountry' because it has a DefiningQuery and no <InsertFunction> element exists in the <ModificationFunctionMapping> element to support the current operation.

我应该自己在edmx中定义它吗？怎么样？

我有这个mainActivity

public class MainActivity extends RoboFragmentActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Crashlytics.start(this);
        //setContentView(R.layout.activity_main);

        Intent intent = new Intent(this, MainActivity_with_Fragment.class);
        startActivity(intent);
        finish();
    }
}

这是我的gradle.build

buildscript {
    repositories {
        jcenter()
        maven { url 'http://download.crashlytics.com/maven' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.14.2'
        classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'crashlytics'

repositories {
    jcenter()
    maven { url 'http://download.crashlytics.com/maven' }
}

android {
    compileSdkVersion 19
    buildToolsVersion "19.1.0"

    defaultConfig {
        applicationId "com.example.stopcall.app"
        minSdkVersion 14
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    } …

有没有办法追加两个字符串构建器？如果是这样 - 它是否比将字符串附加到StringBuilder更好？

运行以下代码,我得到一个例外:

using (var client = new Pop3Client())
{
    client.Connect(provider.ServerWithoutPort, provider.Port, true);
}

我得到的例外情况:

The remote certificate is invalid according to the validation procedure.
