## 进程查找与杀死

### tasklist

  * **Image name** is the name of the executable, e.g. explorer.exe or myapp.exe

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

### taskkill

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

### 完整代码

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```

## 相关知识点

1>nul 意思是不显示命令运行的正确提示
2>nul 是不显示错误提示
一起就是 正确错误的都不显示

> 是重定向符号
>  nul是空设备的意思
>  把提示输入到空设备就不显示了

## 查询程序及命令行参数

```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
```csharp
string a = "test";
string tmp = "est";
string b = "t" + tmp;
Console.WriteLine(string .ReferenceEquals(str1, str2));

```
