Visual Studio 和 string.format 在新行参数中出现问题

本文关键字：参数 问题 新行 Studio string format Visual | 更新日期: 2023-09-27 18:30:43

我覆盖了我的ToString（）方法，我的类包含许多字段。
我只能在最后一个字符串之后有新行，并且只将变量放在下一行。
注意 - 这仅用于视觉目的，我不希望在打印之间分开一行。只是为了在我的 21 英寸屏幕上看到完整的线条而不滚动。

这有效：

    public override string ToString()
    {
        return String.Format("{0}, IsAccessible = {1}, NetworkAddress = {2}, Manufacturer = {3}, Model = {4}, Firmware = {5}, Driver = {6}, MacAddress = {7}, Scenes count = {8}",
            base.ToString(), IsAccessible, NetworkAddress, Manufacturer, Model, Firmware, Driver, MacAddress, Scenes.Count);
    }

但这不起作用（相同的代码，仅在第 4 个参数后按回车键）： 

    public override string ToString()
    {
        return String.Format("{0}, IsAccessible = {1}, NetworkAddress = {2}, Manufacturer = {3}, Model = {4},
        Firmware = {5}, Driver = {6}, MacAddress = {7}, Scenes count = {8}",
            base.ToString(), IsAccessible, NetworkAddress, Manufacturer, Model, Firmware, Driver, MacAddress, Scenes.Count);
    }

Visual Studio 和 string.format 在新行参数中出现问题

String是引号之间的一行中的符号序列。

"one two" - is string.
"one
  two" - is an error.

可以在 C# 中通过串联有效字符串来创建多行字符串：

String s = "one" + Environment.NewLine + 
           " two";

或在字符串前添加@ 

String s = @"one
             two";

使用逐字字符串，以 @ 字符开头的字符串：

public override string ToString()
{
    return String.Format(@"{0}, IsAccessible = {1}, NetworkAddress = {2}, Manufacturer = {3}, Model = {4},
    Firmware = {5}, Driver = {6}, MacAddress = {7}, Scenes count = {8}",
        base.ToString(), IsAccessible, NetworkAddress, Manufacturer, Model, Firmware, Driver, MacAddress, Scenes.Count);
}

我唯一能想到的如下：

public override string ToString()
{
    return String.Format(
        "{0}, IsAccessible = {1}, NetworkAddress = {2}, Manufacturer = {3},"
        + " Model = {4}, Firmware = {5}, Driver = {6}, MacAddress = {7},"
        + " Scenes count = {8}",
        base.ToString(), IsAccessible, NetworkAddress, Manufacturer, Model, Firmware, Driver, MacAddress, Scenes.Count);
}

试试这个：

string temp_var = @"{0}, IsAccessible = {1}, NetworkAddress = {2}, Manufacturer = {3}, Model = {4},
          Firmware = {5}, Driver = {6}, MacAddress = {7}, Scenes count = {8}";
temp_var = string.Format(base.ToString(), IsAccessible, NetworkAddress, Manufacturer, Model, Firmware, Driver, MacAddress, Scenes.Count);
return temp_var;

只需将值分配给字符串变量即可。
