In C#, you can use the Substring method to extract a specific portion of a string. There are two different versions of the Substring method.<\/p>\n

    \n
  1. Substring(int startIndex): Extracts the substring starting from the specified startIndex position to the end of the string.<\/li>\n
  2. Extract a substring starting from the specified startIndex position with a length of ‘length’.<\/li>\n<\/ol>\n

    Here is an example of using the Substring method to extract a portion of a string:<\/p>\n

    string<\/span> str = \"Hello, World!\"<\/span>;\r\nstring<\/span> substring1 = str.Substring(7<\/span>); \/\/ \u4ece\u7d22\u5f15\u4e3a7\u7684\u4f4d\u7f6e\u5f00\u59cb\u622a\u53d6\uff0c\u7ed3\u679c\u4e3a\"World!\"<\/span>\r\nstring<\/span> substring2 = str.Substring(7<\/span>, 5<\/span>); \/\/ \u4ece\u7d22\u5f15\u4e3a7\u7684\u4f4d\u7f6e\u5f00\u59cb\uff0c\u622a\u53d6\u957f\u5ea6\u4e3a5\u7684\u5b50\u5b57\u7b26\u4e32\uff0c\u7ed3\u679c\u4e3a\"World\"<\/span>\r\n<\/code><\/pre>\n
    In this example, str.Substring(7) will return a substring starting from index 7 to the end of the string, which is “World!”. On the other hand, str.Substring(7, 5) will return a substring starting from index 7 with a length of 5 characters, which is “World”.<\/p>\n","protected":false},"excerpt":{"rendered":"
