Trim的使用 C#

Trim的使用

These methods are designed for trimming characters from strings.
Here's a breakdown of each method, along with examples of their usage:

1. Trim(char trimChar):

• Removes all leading and trailing instances of a specific character from a string.

• Example:

string myString = "  Hello World!  ";
string trimmed = myString.Trim(' ');  // trimmed will be "Hello World!"

2. Trim(params char[]? trimChars):

• Removes all leading and trailing occurrences of characters from a specified array.

• If trimChars is null or empty, it removes whitespace characters.

• Example:

string myString = ",,Hello,World,,";
string trimmed = myString.Trim(',');  // trimmed will be "Hello,World"

3. Trim():

• Removes all leading and trailing whitespace characters from a string.

• Example:

string myString = "\t  This is a string with whitespace. \n";
string trimmed = myString.Trim();  // trimmed will be "This is a string with whitespace."

4. TrimEnd():

• Removes all trailing whitespace characters from a string.

• Example:

string myString = "This is a string with trailing whitespace  ";
string trimmed = myString.TrimEnd();  // trimmed will be "This is a string with trailing whitespace"

5. TrimEnd(char trimChar):

• Removes all trailing occurrences of a specific character from a string.

• Example:

string myString = "Hello!!!!";
string trimmed = myString.TrimEnd('!');  // trimmed will be "Hello"

6. TrimEnd(params char[]? trimChars):

• Removes all trailing occurrences of characters from a specified array.

• If trimChars is null or empty, it removes whitespace characters.

• Example:

string myString = "Hello...World...";
string trimmed = myString.TrimEnd(new char[] { '.' });  // trimmed will be "Hello...World"

7. TrimStart():

• Removes all leading whitespace characters from a string.

• Example:

string myString = "  This is a string with leading whitespace.";
string trimmed = myString.TrimStart();  // trimmed will be "This is a string with leading whitespace."

8. TrimStart(char trimChar):

• Removes all leading occurrences of a specific character from a string.

• Example:

string myString = "*********Hello World*********";
string trimmed = myString.TrimStart('*');  // trimmed will be "Hello World*********"

9. TrimStart(params char[]? trimChars):

• Removes all leading occurrences of characters from a specified array.

• If trimChars is null or empty, it removes whitespace characters.

• Example:

string myString = "00012345";
string trimmed = myString.TrimStart(new char[] { '0' });  // trimmed will be "12345"
