我的任务
分享C#中怎么将矩阵从textbox中提取出来，求大神修改代码，使我的计算器能完美运行
还有怎么将数组从textbox里显示出来，我因为不会才用的字符串，求大神指教
我的运算代码写出来了，求大神指教
这是矩阵的设计

矩阵显示你用Grid显示不就行了？组织成Table，然后bind

直接从 textBox1.Lines 中切割出各列，而不是从 textBox1.Text 中切割出行列
先检查
textBox1.Lines.Length 是否等于 a
textBox1.Lines[0].Split(sp).Length 是否等于 b
然后再做后续处理
处理过程中对每一行都要检查 textBox1.Lines[i].Split(sp).Length 是否小于 b

数组超出索引了，单步调试下，看看具体数值多少

那数组索引超出的原因是啥，我看我的那几个数组的元素个数没有错误呀？
