如何在字符串开头删除空格？

Question

Let's say I have following string: string test = " False";

I can't loop the characters of the string because I need to do this for 1744 strings, then it would be a lot of work.

Do you know if there is a method from Microsoft that I can use to delete this whitespace?

Like this: string test2 = test.DeleteFirstWhitespace();

Thanks

Answer 1

您可以在C＃中使用TrimStart ：

string test2 = test.TrimStart()

Answer 2

As everyone else has pointed out, there is a trim function. Make sure to remember that a string is immutable, so when you call test.Trim(), it will not modify the test variable, it will return a new string:

string trimmed = test.Trim();
// or
string trimmed = test.TrimStart();

Answer 3

如何使用trim()函数：

string test = test.trim();

Answer 4

test.trim();
此方法从字符串的开头和结尾删除空格。

Answer 5

You can use:

• String.Trim() to remove all leading and trailing white-space characters
• String.TrimStart() to remove only leading white-space characters
• String.TrimEnd() to remove only trailing white-space characters

All these have additional overloads which let you specify an array of custom characters also to be removed.

Answer 6

Speaking of Java : String.trim() . Here is the link to the API documentation: String.trim()

Answer 7

In java:

Use trim() to remove the whitespaces around a String:

String test2 = test.trim();

Returns a copy of the string, with leading and trailing whitespace omitted.

Answer 8

I can also use the method TrimStart()

like this:

string test2 = test.TrimStart(' ');
