第二个值是一个巨大的字符串，通过存储它nvarchar(max)从 c# 代码检索时有很多空格想要删除它。在 C# 中检索 nvarchar(max) 值的兼容数据类型是什么？我想检索此值

如何在 SQL Server 的列中插入长字符串值

我认为您可以使用常见的SqlCommand

对于第二个参数，您可以执行以下操作

cmd.Parameters.Add("@Value", SqlDbType.VarChar);
cmd.Parameters["@Value"].Value = longString;

其中longString是查询参数

我猜您是通过 C# 应用程序生成上述查询的。 使用以下命令消除多个空格：

string input = "This is   text with   far  too   much     whitespace.";
string pattern = "''s+";
string replacement = " ";
Regex rgx = new Regex(pattern);
string result = rgx.Replace(input, replacement);
