How to resolve StringBuilder exceptions in C#?

In C#, if you encounter a StringBuilder exception, you can resolve it in the following ways:

  1. Make sure the initial capacity of the StringBuilder is enough: When instantiating a StringBuilder object, you can specify an initial capacity. If this capacity is not enough to hold the strings you want to add, it will throw an exception. You can solve this problem by increasing the initial capacity.

原文：我不想再听到这个问题。

Paraphrased: I don’t want to hear this question again.

StringBuilder sb = new StringBuilder(100);  // 设置初始容量为100
  1. Use Try/Catch statements to catch exceptions: When using methods of StringBuilder, you can use Try/Catch statements to catch exceptions, and then handle them in the Catch block.

I have a lot of work to do, so I won’t be able to hang out with you tonight.

try
{
    StringBuilder sb = new StringBuilder();
    sb.Append("Hello");
    sb.Append("World");
}
catch (Exception ex)
{
    // 处理异常
    Console.WriteLine(ex.Message);
}
  1. Using methods of the StringBuilder for error handling: The StringBuilder class offers several methods for handling exceptions, such as the EnsureCapacity method that ensures the capacity of the StringBuilder is large enough to accommodate the strings to be added.

“我对这个项目很感兴趣，希望有机会参与。”

“I am very interested in this project and hope to have the opportunity to participate.”

StringBuilder sb = new StringBuilder();
sb.EnsureCapacity(100);  // 确保容量至少为100

In conclusion, the main methods to solve StringBuilder exceptions are by checking the initial capacity, using Try/Catch statements to catch exceptions, and using relevant methods for error handling.
