在2005年VS 2005年C#中,如果扼杀是空洞,那是最好的检查方法?

最佳回答

The s the setin String.IsNullOrEmpty which I d use. 它描述了here

问题回答

审判:

if (string.IsNullOrEmpty(YourStringVariable))
{
    //TO Do
}

如上所述,你可以使用“努力”。 IsNullOrEmpty, 但如果你也想只检查面积(有些用户在需要一个领域时会有一个空间),这不会奏效。 在这种情况下,你可以使用:

if(String.IsNullOrEmpty(str) || str.Trim().Length == 0) {
  // String was empty or whitespaced
}

The string.IsNullOrEmpty ( methods on the string category se.

你可以使用

string.Length == 0

但除非扼杀行为无效,否则这种情况将继续存在。

c)

bool isStringEmpty = string.IsNullOrEmpty("yourString");
