去除字符串中的所有-号

要去除字符串中的所有减号（-），你可以使用编程语言中的字符串操作函数或方法。这里提供几个常见编程语言的例子：

1. **Python**:

def remove_dashes(input_string):
    return input_string.replace("-", "")

input_str = "example-string-with-dashes"
new_str = remove_dashes(input_str)
print(new_str)  # 输出: examplestringwithdashes

2. **JavaScript**:

function removeDashes(inputStr) {
    return inputStr.replace(/-/g, "");
}

let str = "example-string-with-dashes";
let newStr = removeDashes(str);
console.log(newStr);  // 输出: example-string-with-dashes

3. **Java**:

public String removeDashes(String input) {
    return input.replaceAll("-", "");
}

String inputStr = "example-string-with-dashes";
String newStr = removeDashes(inputStr);
System.out.println(newStr);  // 输出: example-string-with-dashes

4. **C#**:

using System.Text.RegularExpressions;

public string RemoveDashes(string input)
{
    return Regex.Replace(input, "-", "");
}

string inputStr = "example-string-with-dashes";
string newStr = RemoveDashes(inputStr);
Console.WriteLine(newStr);  // 输出: example-string-with-dashes
